Has anyone received the following error? Ran into it while trying out the UI locally after running the deploy script for the first time - have tried to look around the web for answers with minimal success so far:
Error: call revert exception (method="fetchMarketItems()", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.4.0)
All of my code is the same as the source code currently, please let me know if anyone has any ideas as to why this is happening!
Delete artifacts folder and compile hardhat
Hi folks, I think I found the solution.
You can find
loadNFTs()function inpages/index.js. We use theJsonRpcProviderto get the provider. That's the point. You must provide RPC url of the testnet where you want to deploy NFT contracts. In my case, I targeted thebsctestnet, so I provide the RPC url of thebsctestnettoJsonRpcProviderconstructor. Maybe you can keep the url in theconfig.jsfile. That's all. Cheers~can you share code how? i am not clear
from where to get this rpc url?
In your metamask settings->networks.
Please check the screenshot.
sorry not able to understand
Okay, let me show another screenshot.
If you are trying to find RPC url of ropsten testnet, click the network name and simply copy the RPC url
That's all. Hope this is helpful for you. Thanks.
Thank you! It has been a while since this post but I just wanted to thank you, this solved my problem when deploying it to a testnet (Rynkeby in my case!)
@legendaryphoenixicarus I just created an account to thank you for the JsonRPCProvider code you posted above. I was struggling and this solved my problem. thanks so much!
@Silvia Barros @Sir Baller @legendaryphoenixicarus
thanks for your suggestions. and i want to deploy it to a testnet (ropsten),after i follow these suggestions and change the code , i meet a question (also when i deploy it for mumbai) ,it likes this (Error HH8: There's one or more errors in your config file: * Invalid account: #0 for network: ropsten - Expected string, received undefined). can u help me solve the problem or share me the hardhat.config.js file? thank you.

@zkimhom
You should pass your wallet private key from
.envfile to the account property.ok i got it. thank you so much
"Delete artifacts folder and compile hardhat" this does not solved it for me
Follow this instruction:
To force a compilation you can use the --force argument, or run npx hardhat clean to clear the cache and delete the artifacts.
Was having the same problem and going crazy, my code was exactly like the tutorial, but one thing: the hardhat version.
After downgrading the hardhat version from 2.6.0 to 2.4.1 the issue has been fixed. (don't forget to delete the artifacts folder and run compile hardhat)
command please?
I'm having no problems with version
^2.8.2so I'd try that one first.to change versions, do
npm install hardhat@^2.8.2and just replace the numbers at the endI had the same problem.
The problem was solved by resetting the saved data by executing the following command described in the GitHub repository> README.
Probably the error is due to some problem with the saved data.
but i want to deploy this to ropsten not localhost so other can interact with it
This post is old so this response probably won't help the original poster but it might help anyone else with this same error as I had. It's possible if you have his error that you're using the latest version of Node i.e., 17 which prefers IPv6 in it's search order. So when you're asking hardhat to perform it's node operation and it's creating a loopback of http://::1:8545 (IPv6) vs 127.0.0.1 which is the IPv4 version of the loopback. When you run the deploy script command (while using the IPv6) you'll have to use that 'hardhat' modifier for the network vs localhost or the command will fail and you'll get this error in your marketplace. To fix it you can change the DNS search order in Node 17 or use NVM to install an earlier version of Node.js. happy hunting!
I updated my localhost to ipv6 nothing change
Probably you deploy smart contract to local hardhat node and later you suspend it.
1- Make sure you installed hardhat
2- If you want to deploy on localhost, make sure run
npx hardhat nodein other terminal window.3- Redeploy it either localhost node or test networks (no need to start node on local) like Mumbai
npx hardhat run scripts/deploy.js --network localhosti'm getting this error and also
TypeError: marketContract.fetchMarketItems is not a function.
I've managed to upload to vercel and get it working, can create an NFT but nothing is displayed in dashboard or my items or marketplace front page.
I don't think the images are being sent to IPFS.
Anyone help?
I am getting this Error after createItem function (on click Create an Asset button). I have same RPC in Metamask and the JSONRpc. Please guide me through this. Tried to do with different accounts but didn't work.

change your chainID to 31337 in your metamask wallet if you are deploying to the localhost testnet
yes!1
I've the same problem but no-one seems to be able to answer this. I can create NFTs but they don't show in marketplace to be able to buy
This is happening because of a Mumbai error, outputting the wrong contract address. This causes the NFT contract to not approve the Marketplace's contract address to sell the NFTs. Redeploy with this script, by replacing
main()indeploy.jswith:Thanks for this, i've replied to your same post in github.
Thanks this work for me for nonce error on deploy multiple contracts
Same Issue. Its saying
"execution reverted: ERC721: transfer caller is not owner nor approved"my error message is
Error: call revert exception (method="fetchMarketItems()", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.4.0)
and others related to getting MarketItems.
Yes for some reason the market.address (in the deploy.js file) doesnt console.log the address of your NFTMarket address but some random one (same thing for the NFT contract address). What you can do is look at the transaction created by your Mumbai wallet. Find this transactions then get the contract's addresses of these transactions and update them accordingly in your config.js file.
what you can do is redeploy on mumbai and instead of console.log address console.log(market.deployTransaction.hash) and console.log(nft.deployTransaction.hash) . This will give you the transactions hashes then go to mumbai.polygonscan.com/ and enter these transactions hashes in order to find the correct contracts addresses. Update your config.js accordingly.

Hi, thanks for the reply and image, i've got it to work by adding the adding the package.json and package-lock.json from the repository then npm i, after npm run dev to localhost 3000 got a 'network RPC' but that went when i added the chainstack link to index.js for loadNFTs
const provider = new ethers.providers.JsonRpcProvider("matic-mumbai.chainstacklabs.com").
I can now create NFTs and these show in the dashboard for any user and after making changes above also in the marketplace, but i can't click on the Buy button, nothing happens.
Thanks
can you please share your git repo, I am having issues in the NFT contract.
Hi, i don't have a git repo for my site, i used localhost then vercel cli
can you share it somehow please then?
I've not changed the NFT contracts. They're the same as in the git repo from dabit3 here github.com/dabit3/polygon-ethereum....
I got the solution i tried from a discussion on the dabit repo github.com/dabit3/polygon-ethereum...
I use github and do send files to it bit for some reason they don't upload to the selected repository, i have about 23 repositories i use for various things but this website, and others, are cloned locally then edited and uploaded to vercel by CLI, i can't get them to work on netlify or heroku
If you deploy contract on localhost on port:8545 then make sure to connect to same port in metamask. And also use only JsonRpcProvide() instead of matic or any other provider.
you need to re-deploy the contract and change nftContract address and nftMarket address in config.js
I ran into issues with Infura, and with ipfs http server.
Infura requires you to create a billable account to use Polygon now, and you'll need to make another project on there for the IPFS part to get a project id and key specifically for IPFS.
After reading docs, I ended up going with the latest version of ipfs http server (
^55.0.0at time of writing) and doing the following:I guess things are changing quickly! π
Thanks @arielbk, The public IPFS gateway was deprecated by INFURA in August 10 2022.
Please read the details here.
I've created the PR for uploading Files on IPFS using Pinata Gateway.
It's absolutely free to create your own project on Pinata and you can get the key pairs for your project.
I ended up signing up for an account at maticvigil.com which doesn't need a credit card
and so how do the IPFS API url s change? do they also use Projet ID and secret KEY stuff? This will be immensely useful.............thanks in advance
Hey, can you please show an example on how you did that ?
Could you please show an example text on how to get this in the code? I donΒ΄t really understand it. I think IΒ΄m having the IPFS problems as well.
Thank you @arielbk! Really helpful!
I'll supplement some details.
First, put the infura personal project id and project secret to
.envand make sure to add.envto.gitignore:Second, set env in
next.config.js:Third, change the code in
create-item.jsThe
importandconst:And in the function
CreateItem():Hey, I tried everything here but I get message: "Request failed with status code 400"
Do the suggestion above with the Auth header and also...
In your Infura IPFS Project, enable the dedicated gateway then replace:
const url =
https://ipfs.infura.io/ipfs/${added.path}const url =
https://DEDICATED_GATEWAY_URL/ipfs/${added.path}This requires a credit card on file on Infura.
Does this solution take care of creating an IPFS project (giving credit card info) ??? i dont see how.
Yes because it allows you to use the dedicated gateway which gives you a URL like - nftmarketplace.infura-ipfs.io. Otherwise the old way in the tutorial no longer works on Infura.
Hi @arealclimber and @joninsley appreciated, able to run the flow, but may I know what is the differences between client.add and client.pin.add.
Thanks so much!
I had same issue with JsonRpcProvider, so I did
Deploy again on mumbai test net, copy new contract address to config file and voila
PSD. Remember to have same url in metamask wallet, hardhat config file and index.js
There is a small bug when buying an item when the tokenId and itemId do not match.
How to reproduce:
1- Go to /create-item, mint an item A with price X, but do not list it.
2- Mint an Item B with price Y, then list it.
3- Go to index and try to buy item B.
Result: "Please submit the asking price in order to complete the purchase".
Expected result:
Purchase successful.
Fix:
1- In index.js on the function loadNFTS add
itemId: item.itemId.toNumber(),to the object item.2- When calling createMarketSale the second argument should be nft.itemId.
As I've finished typing all this I've noticed that it has been fixed in the github repo github.com/dabit3/polygon-ethereum...
Well, at least now you know if you are looking for a solution here
yes correct, the same fix applied!
If you are going though this tutorial, I've build a slightly more cooler NFT Marketplace based on this blog post that helped me land a job 6 months ago, and for that I thank Nader and several other free content providers.
Granted it was my first time playing with Next, and there are several things I would have done differently, but hey have a look, its not bad:
nft-marketplace-dusky.vercel.app/c...
github.com/UrbanWill/nft-marketplace
Thank you! Appreciate the help!!
if you have a setForSell function in the Market contract say after a user buys then decides to sell again, will you then need to transfer the token to the market address? like IERC721(nftContract).transferFrom(msg.sender, address(this), tokenId). Because I have tried this and it is giving me error 'ERC721: transfer caller is not owner nor approved' but the owner of the token is the one making the transfer. Maybe im not doing something right. Please help

Hope it helps ;)
There's a way to change the deploy script w/o changing the contract itself. This is happening because of a Mumbai error, outputting the wrong contract address. This causes the NFT contract to not approve the Marketplace's contract address to sell the NFTs. Redeploy with this script, by replacing
main()indeploy.jswith:Hey, I'm having the same problem :( were you able to solve it since you posted this?
I have not. Still looking for a solution
Solved my issue yesterday by writing a custom function to tranfer tokens on my NFT contract. Like this:
And in my Market Contract:
Don't know all the implications of this solutions and if it may fail or cause security issues somehow but it solved my problem for know.
Thanks that solution works but I agree with the implications it may bring if any. Thank you though! Ill update you if I find another stable solution.
my pleasure! Keep me posted about the solutions you may find.
Hi, thank you for posting this, i would like to use your function on my code but it says "onlyItemOwner(itemId)" never used, am i missing something? thanks again!
Hey there! its a modifier that you're missing. I added this to my contract so I can use it in functions to ensure only the item's owner can execute it:
thanksss
Amazing article as always @dabit3
One small error I found is on
sample-test.jsinstead of:it should be
Thank you! And thanks for the heads up, fixing this now!

If you are running on local, you haven't compiled or tested your code and hence the artifacts are not generated.
If you are trying to build on vercel, this will come cause again the artifacts are missing. The general practice is not to commit those. Add a compile (or test) command to your build script before building nextjs.

Hi, i'm really stuck on this and have been trying to figure it out for hours, did you manage to figure it out?
hm, did You try figure out this: '' error - ./pages/index.js:11:0 '' *** index.js 11 code line
time is the master , and time could be disaster .. .
for me worked good enough to go and make tests :
' 'change => '../artifacts/contracts/Market.sol/NFTMarket.json' to ...... '../artifacts/contracts/NFTMarket.sol/NFTMarket.json' ''
After a couple of hours of digging I finally found the solution to this problem
Please elaborate
change => '../artifacts/contracts/Market.sol/NFTMarket.json' to ...... '../artifacts/contracts/NFTMarket.sol/NFTMarket.json'
Hey Nader! This is such a brilliant article and a youtube video. I tried my hands at it and am falling in love with Blockchain.
So, if I am understanding it right, the listing fees should reflect in the owner's account when a certain sale happens right? But I am unable to see it. I will try to revisit the code and figure out why it isn't happening.
Amazing to hear! Yes! This should be the case. Maybe consider bumping the listing fee up high to see it show up, maybe something like equivalent of 100 or 1000 Matic
Thank you so much for replying. Yes, I did try it with 1000 matic. But it was still not working. It was a very stupid mistake from my end. Out of the three accounts on metamask, one was actually not imported using the keys generated in the hardhat node command π I used that account's private key to initialise the market contract lol.
I was tearing my hair in trying to figure out why it wasn't working as the code made perfect sense.
Great work though. Looking forward to the next article. :D How to create a yield farm π
Hi, I too was having this issue and using the hardhat private key worked for me as well. Now my question is how do get this functionality to work with my personal ethereum account?
Hi, I too was having this issue and using the hardhat private key worked for me as well. Now my question is how do get this functionality to work with my personal ethereum account?
i can create items, but when i try to buy nothing happens.
console shows this error: MetaMask - RPC Error: Internal JSON-RPC error.
Object { code: -32603, message: "Internal JSON-RPC error.
(code: 3, message: "execution reverted: Please submit the asking price in order to complete the purchase")
and this one: Uncaught (in promise)
[Note that: its not on matic. i have deploy it to bsc testnet. ]
Could this be it?

Any solution?
Nader, I'm having this problem after having a lot of Nft No market place...
Error: call revert exception (method="fetchMarketItems()", errorArgs=[{"type":"BigNumber","hex":"0x32"}], errorName="Panic", errorSignature="Panic(uint256)" , reason=null, code=CALL_EXCEPTION, version=abi/5.4.0)
It's a new mistake I've never seen anything like it. What can it be?
I had the same problem. If you are testing on Mumbai I suggest changing the RPC provider in both index.js and your metamask account to matic-mumbai.chainstacklabs.com/ instead of rpc-mumbai.matic.today/ . That fixed it for me.
Hi, did you find a solution to this error?
I am having the same issue. π₯
i am facing the same if found solution please share
I honestly cant recall what was the problem, but I think you should compare the code in the video & this article for differences (there are a lot). I had to do line by line debugging to solve some of the errors. it took me more than 2 days to finish this 2 hours tutorial.
all the best.
Hi, I'm having a runtime error in create-item.js when clicking to create the listing! Would appreciate any help, thank you!
The error is regarding: let value = event.args[2]
Restart your hardhat node, Redeploy your contracts, update your config.js with new contract addresses. Set MetaMask custom nounce to 0 (I had to do this to deal w/ another error) and then update the nounce with each following transaction.
hth
Thank you this worked. I also had a misconfiguration in my metamask account. Can you please explain why I have to manually set the nonce? How could I expect an actual user to do this?
if you get the "nonce too high" error, do this: medium.com/@thelasthash/solved-non...
When I redeploy the contract, I dont get any of the console logs, but it says "Done in 1.71s.", is there any reason I am unable to see the addresses?
I had similar in my case it was that i had to re-run deploy.js command.
Hi i having this same event.args[2] you found any solution?
Hi also have the same issue, any solutions?
Did you find a soludtion for this?
For this part
it seems like the intention is to get the
MarketItemCreatedevent (otherwise I think that event goes unused)? But it actually gets theTransferevent. Functionally it's equivalent because both havetokenIdas their third arg, but it's a little unclear what the intention is.Hi Matt,
Did you manage to find a solution to this error?
Hope to hear from you
Hi, I had the same error it was because I wasn't connected to the correct account in Metamask.
Make sure your metamask local network is on the same port provided when you run "npx hardhat node" probably " 127.0.0.1:8545/" and then import the an account to metamask using any of the private keys given and test it again
Hi Amo,
I followed your instructions but still having the same issue.

Various forums online seem to suggest that I need a receiver function, but that doesn't fix the problem for me. Any help would be greatly appreciated!
why is this error coming have you figured it out yet? because I was facing the same error but it probably was due to some another reason.
It's still happening...
Hey all, there's currently a bug on Mumbai causing deployed addresses to be incorrect. This is causing the constructor of the
NFTcontract to approve the wrong address for NFT purchases (because it uses the address of the Market deployment for approval) β causing the annoying"execution reverted: ERC721: approve caller is not owner nor approved for all"error.Try using Mainnet (yes, you'll have to use real money) but it works!
Reference: github.com/nomiclabs/hardhat/issue...
Here's a workaround deploy script that will make it work on Mumbai. Replace
main()indeploy.jswith:Thank you so much, finally it solved after 3 days of suffering.
Thank You again.
what did you do?
I have tried everything when it comes to this error:
Error: call revert exception (method="fetchMarketItems()", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.4.0)
Everybody else here seems to have fixed it by providing the RPC url in the
const provider = new ethers.providers.JsonRpcProvider
But for some reason I keep getting the same error anyway, anybody have any idea where to look? :(
Yes for some reason the market.address (in the deploy.js file) doesnt console.log the address of your NFTMarket address but some random one (same thing for the NFT contract address). What you can do is look at the transaction created by your Mumbai wallet. Find this transactions then get the contract's addresses of these transactions and update them accordingly in your config.js file.
Thank you very much! How do I look at the transactions created by the Mumbai wallet?
what you can do is redeploy on mumba and instead of console.log address console.log(market.deployTransaction.hash) and console.log(nft.deployTransaction.hash) . This will give you the transactions hashes then go to mumbai.polygonscan.com/ and enter these transactions hashes in order to find the correct contracts addresses. Update your config.js accordingly
This fixed it. I now have it deployed the project and its working on mumbai. Once again, thank you so much! I have been going crazy trying to figure this out.
Sure np. Ran into this issue last night as well. Just weird that nft.address logs another address...
where is console.log? (to "instead of console.log address .....") (jan 10 post)
where is console.log file to get market.deployTransaction.hash and nft.deployTransaction.hash?
i have really tried everything

Hey Nader, I wanted to thank you so much for this post and for this wonderful job!
I'm learning a lot and demonstrating to my close friends... Do you have any complete courses?
I was able to run perfectly and execute, I wanted to know how I could implement it so that the assets that were bought can have their prices changed and sell again.
From what I understand after you buy the NFT you have nothing to do with it anymore.
That's right??
Have you been able to find a solution to this ?
I keep getting the following error under my pages, when attempting to deploy to Vercel - but I'm not sure how to resolve it, since I added my 'artifacts' folder to my .gitignore file:
Module not found: Can't resolve '../artifacts/contracts/NFTMarket.sol/NFTMarket.json' in '/vercel/path0/pages'Would love some assistance, please
So the only thing I have been able to figure out for deployment is to ignore the artifacts folder (not sure why, probably it's a security issue) except for the two JSON files. I added this to my .gitignore to make it work:
#Hardhat filescache
artifacts/*
!artifacts/contracts
!artifacts/contracts/*
!artifacts/contracts/NFT.sol
artifacts/contracts/NFT.sol/*
!artifacts/contracts/NFT.sol/NFT.json
!artifacts/contracts/NFTMarket.sol
artifacts/contracts/NFTMarket.sol/*
!artifacts/contracts/NFTMarket.sol/NFTMarket.json
Hope that helps!
Thanks @mataspigaga. I forgot I that also posted on dev.to - but thankfully, I did manage to figure out what was causing the deploy to error out in my own instance. See the following link:

I'm stuck on this error
Unhandled Runtime Error

Source

The issue may be because of this line:
const provider = new ethers.providers.JsonRpcProvider()
I read the ethers docs, and they recommend JsonRpcProvider() for local nodes, for others they recommend getDefaultProvider() or Web3Provider(web3.currentProvider).
The other pages use Web3Provider, it's only index.js that uses the bad one.
So the fix for me was to make this change to index.js:
const provider = new ethers.providers.Web3Provider(web3.currentProvider)
And now I'm connected to and playing with the network!
You need to define networkId to the provider - ethers.getDefaultProvider('ropsten')

I'm getting the same error. Anyone knows how to solve this?
Got same error while testing contracts. This error happens as i try to call function that takes bool as parameter.
I'm getting the same error. Can anyone help?
Hi, i hope you're well
Firstly thank you for putting this together it's really amazing!
I've spent a few days going through it slowly and using your code examples above to avoid any syntax errors and i'm nearly at the end but am getting the following error and wondered if you could help?

Has anyone received this error while buying NFT from Home page?
Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.5.0)
I did some little digging and found that the error is coming out of function buyNft() in index.js. The error arises when I createMarketSale(). See code snippet below.
const price = ethers.utils.parseUnits(nft.price.toString(), 'ether')
const transaction = await contract.createMarketSale(nftaddress, nft.itemId, {value: price})
Full code: github.com/dabit3/polygon-ethereum...
The same function works perfectly fine when used in tests. Appreciate any help.
Hi dmk,
I solved the problem. My bug was I was giving the wrong contract address to contract.createMarketSale()
Earlier, I was my code looked like,
const price = ethers.utils.parseEther(nft.price.toString());
createMarketSale(nftMarketplaceAddress, nft.tokenId, { value: price });
The correct code should be,
const price = ethers.utils.parseEther(nft.price.toString());
createMarketSale(nftTokenAddress, nft.tokenId, { value: price });
bump for this, anyone has a solution?
I got the same error, did you solved?
Thanks. I try to deploy to the ropsten network but I have a mistake.
It is Error: call revert exception (method="fetchMarketItems()", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.4.0)
How can I fix it?
i am facing the same if you have solution please share solution

I'm getting the following error:

Awesome tutorial! I've noticed when you create a market item with
createMarketItem()on thecreate-itempage, theitem.owneranditem.sellervalues are not the same. Is this on purpose or should these values be the same? If they are the same, the item would show up on themy-assetspage. Is the creator of the item not initially the owner?hey there, I'm currently working on this project and I'm receiving such errors... Can someone please advice me on what to do next? Thank you in advance :)

Hi, I had the same error it was because I wasn't connected to the correct account in Metamask.
Make sure your metamask local network is on the same port provided when you run "npx hardhat node" probably "127.0.0.1:8545/" and then import the an account to metamask using any of the private keys given and test it again
This fixed it for me, thanks!
Hi, I had the same error ...pls help me to solve that
Hello everyone :)
I have this error in my-assets.js:
Unhandled Runtime Error
Error: call revert exception (method="fetchMyNFTs()", errorSignature=null, errorArgs=[null], reason=null, code=CALL_EXCEPTION, version=abi/5.0.0-beta.156)
I copied and pasted the code from Github, I already looked everywhere on the Web but I can't figure it out because I don't fully understand what it is
I feel so desperate and frustrated, so useless :(
You are calling the JsonRpcProvider but initialising it with a public rpc url while running a local node. Remove that and it should work fine. ππΌ

Hey Nader, by the end of this post you mention about publishing a tutorial about showing how to use Polygon with The Graph, however I can't find it under your profile here.
Were you able to put this together or is somewhere else? A link to it would be very appreciated.
Thank you!
I had a problem with reading the .env file from in the hardhat.config.js file seemed like this was not explained in the tutorial. I fixed it by doing this :
const dotenv = require("dotenv");
dotenv.config();
accounts: [
${process.env.privateKey}]Is this the right way to do it ?

This is awesome, thanks @dabit3 ! Question. In the deploy script, what's the difference between deploying the NFTMarket contract and NFT contract? The former calls
deploy()with no args, whereas the later callsdeploy(NFTMarket.address).If you look at the constructor for NFT smart contract, it requires the NFTMarket address.
I have it all deployed on mumbai testnet and it seems like it is working. But when I try to create an NFT, it doesn't seem to work. It goes all the way to the transaction being successful in the wallet (transaction complete in metamask). But nothing happens to the "sell digital assets page" its just still. Then when I look at the "Home" there is no items in the marketplace being displayed.
Can anybody please help? Maybe this has something to do with Infura wanting to have a separate project for IPFS now. But I donΒ΄t understand where IΒ΄m supposed to put the IPFS projectid and secretid in the code? :(

Amazing ! Juste went though it today. Now if we were to use Polygon, the contracts would need to handle both tokens right ? Because having the prices in ETH on Polygon would not work right ? Or I guess the entire market place would need to be on Polygon. Either way amazing work !
PS: I had some trouble with the JsonRpcProvider function which would still return localhost. Make sure you update .secret BEFORE deploying the Smart Contracts to the Mumbai testnet. (Already stated in the article, but I tend to read diagonally... )
Hello,
thanks a lot for this super-interesting article. I have a question:
How do you disconnect the wallet?
I've connect the wallet for the first hardhat account but I don't know how to disconnect metamask to log with another account.
Thanks
I got this error :
Error HH8: There's one or more errors in your config file:
module.exports = {
defaultNetwork: "hardhat",
networks: {
hardhat: {
chainId: 1337
},
// unused configuration commented out for now
mumbai: {
url: "rpc-mumbai.matic.today",
accounts: [process.env.privateKey]
}
},
solidity: {
version: "0.8.9",
settings: {
optimizer: {
enabled: true,
runs: 200
}
}
}
}`
Not sure why
address(0)is used instead ofaddress(this)to represent that the market owns the NFT?address(this)is passed totransferFrom, so I think they should be consistent.I agree with this! Have you tried it?
Thanks Nader for a wonderful tutorial, I just wonders how we have listing fee of 0.025 ETH, but once we changed to MATIC network, we don't have any ETH in our account, how can we pay this fee? We pay it with MATIC (converted to ETH)?
I think it's denominated in MATIC here actually.
PLEASE HELP!!!!!
After running the script "npx hardhat test" for testing the contract, I am getting this error
NFTMarket
Should create and execute market sales:

PLEASE HELP

hello i am having the same problem. did you solve the problem?
First delete the artifact folder, after that in the "test" file try replacing NFTMarket with NFTMarketplace and then rerun the hardhat script.
The following procedure worked for me
hi, I have some problems with this prj, can I contact you for your help?
Sharing in case anyone encounters with the same issue:
In order to configure the Mumbai testnet in Metamask, I had to use the following RPC URL
https://rpc-mumbai.maticvigil.com/(as stated in the docs docs.polygon.technology/docs/devel...) instead of the one in the article, which showed a wrong Chain ID error.When i deploy to matic using
405 Not Allowednpx hardhat run scripts/deploy.js --network mumbai
I get this :
HardhatError: HH110: Invalid JSON-RPC response received:
405 Not Allowed
My hardhat.config.js file :
`require("@nomiclabs/hardhat-waffle")
module.exports = {

Hello! I have followed the tutorial till the last. But I am facing issue in getting list of item which user just buy. I am able to successfully buy items but I am not getting those item in my items by calling fetchMyNFTs function.

install all the packages related to hardhat again.
do them one by one just to make sure they're installed correctly. this worked for me
Thank you for the article. It was really helpful. I am in the section of running the program in the local network and I got it to work up to the gas fee in metamask. However looking at the video another metamask tab appears to put the item in sale but this does not appear in mine.
This is probably why the transaction does not occur even after pressing "Create Digital Asset."
Do you know how to fix this issue? Thanks
Superb walkthrough Nader, gracias!
Had to change
import web3 from 'web3'toimport web3 from 'web3-utils'in create-item.jsOtherwise very easy to get it up/running.
"Error: network does not support ENS (operation="getResolver", network="maticmum", code=UNSUPPORTED_OPERATION, version=providers/5.6.1)"
This is the one of two error i'm getting. i'm unable to fix it !! HELP.
Hi Mugiwara, did you ever fix this? I'm getting the same.
What up guys.
So, I forked the github repository,
and tried to deploy it within vercel.com
I got a lot of error alerts then...
watch screenshot
dev-to-uploads.s3.amazonaws.com/up...
So - has that anything to do with the code?
Or in other words: Should I start trying this scrpit out?
Don't want to underrate this work or talk trash here;
just saw some other guys having some problems in deploying it.
Thanks
Hey Nader, thanks for the tutorial! Could somebody help me out? I'm trying to create some custom methods for the MarketPlace contract. In one, I give the buyer the option to resell the purchased item. But I am getting a "execution reverted: ERC721: transfer caller is not owner nor approved"
The strange thing is that if I console log (IERC721(nftContract).ownerOf(tokenId) == msg.sender I get "true"
Hi π
Thanks for the lesson π
It's really helpfully π
One moment: when testing - 'auctionPrice' in sample-test.js must be same as 'listingPrice' in contract. Otherwise test will fail with message: 'Error: VM Exception while processing transaction: reverted with reason string 'Please submit the asking price in order to the complete purchase''.
So set 'auctionPrice' value in test same as 'listingPrice' in contract to pass the test)
Any solutions for this error?

Hi Chaun, Did you find an answer to this problem
Has anyone else experienced an issue when uploading assets? It seems that as I'm logging into meta mask, the rest of the transaction continues. I'm not prompted to approve the transaction and therefor the form just resets.
Any direction would be great.

If any other developers run into issues and are unable to find or troubleshoot the answer to your questions, I recommend checking out Buildspace where you can be supported in discord to complete dapps. I really wanted to finish this lesson but unfortunately could not find the answer to above so am moving on. If anyone knows of good web 3 developer forums where you can get questions answered I would be most grateful to know.

URGENT HELP!!
I wonder.. If you are implement a NFT marketplace like this, In a future version you could want to create users management...etc.
The question is, What data will you store in blockchain and what data should you store in a centralized database of the application? What should be the criteria?
I asked this question in a lot of places but nodoby answer to me a really realiable answer.
I am using this project and having an issue that when anyone purchases the NFT no amount is transferred to seller's wallet when console log the details it shows 0x000000000000000.. as seller's address.
Hey ,
I am using this project and found that no amount is deducted and and send to the seller wallets after the transaction is done.
NFT is transferring but amount is not.
Kindly help in this issue.
I didn't change anything just copy paste the same project.
Hi,
I have watched and followed your youtube video and successfully created NFT Marketplace.
Thanks a lot for this.
I have a question that, I want features to list, categorise, search, filter NFTs.
So how I can save those details and where to save them ?
Should I save nft details on other database like Mysql to perform those queries ?
Or there is any preferred way to do this ?
Thanks a lot.
