Deploying Go To AWS using CDK in 2024

With go.1x being a deprecated runtime in AWS, we need to start using the PROVIDED_AL2023 runtime. There are quite a few tutorials out there that go over deploying Go lambdas, so I wont cover the extreme detail. (I followed this one by Melkey btw ;)) This is meant to fill in the gap if you are getting this pesky error at runtime:

Error: Couldn't find valid bootstrap(s): [/var/task/bootstrap /opt/bootstrap]

Let's say you have a lambda function defined like this with CDK:

const myTestFunction = new lambda.Function(this, "myTestFunction", {
      // This points to where your Go lambda lives
      code: lambda.Code.fromAsset("lambdas"),
      handler: "main",
      runtime: lambda.Runtime.PROVIDED_AL2023 // Because GO_1_X is now deprecated
    });

(this is also assuming your file structure follows Melkey's video)

If you were to just build your lambda like this:

GOOS=linux GOARCH=amd64 go build -o main

You will encounter the pesky bootstrap error. This is because AWS lambda looks for a bootstrap in the folder that you defined in your code block.

Simply change the out file to bootstrap

GOOS=linux GOARCH=amd64 go build -o bootstrap

AWS Lambda will now be able to see your built Go function and your function will be invoked properly.

There might be better ways to do this, but currently I'm new to Go and this worked for me! Hopefully this helps someone out!

TurboRepo Next.js Build Error

I was converting an existing NextJs app into a repo that is managed by TurboRepo to give the ability to add more apps to our frontend system. Everything went great and was super smooth until I tried actually running the build scripts. I copied the configuration settings exactly from the docs and a couple sample repos that I found, yet still I had a unique problem.
Here is a snippet of the error:

app:build: - info Creating an optimized production build...
app:build: - info Compiled successfully
app:build: - info Collecting page data...
app:build: TypeError: Cannot read properties of undefined (reading 'P')

I followed the stack trace and noticed that it was trying to do a webpack import of a component that I created in a UI package. That should be fine, however upon further investigation, I hadn't realized I exported the story from Storybooks. At this time, I don't really have a need to explicitly export stories from ui into any other project, so I just removed it. That seemed to fix the error. Now webpack builds NextJs just fine, and the app functions the same as it did before I made it a monorepo.

Hopefully this helps someone else!
