Do you have a snippet to show us? it will be easier to help/dubug/point you in the right direction if so!
Please how do I add code snippets here? I tried and there was a liquid error.

Did you manage to resolve this? When I pulled your repo, and run your project, I'm not getting the error from
http://localhost:3000/auth/register.I added the debug line from the react docs for debugging this. Removing
useHistory(and references tohistory) did not make a difference.I suspect it is going to be a mismatching react issue. I'd suggest remove your
node_modulesdirectory, and removingpackage.lockandyarn.lock. Then run$ yarn.$ react-router-domso, also add that with yarn$ yarn react-router-domOkay! Still have not resolved it yet.
I'm just going to apply your recommendations and give a feedback.
Yes! the issues is with mismatching versions of react.
Clarification please: I installed yarn because npm was working so well for me, but now I think it is fine.
Do I really need both of them (yarn and npm) installed now? I don't know if that could be one of the causes but I just want to know.
Again, thanks so much @jen , I am really grateful
yarn and npm are both package managers, but they will install slightly differently. It doesn't matter which you use, just whichever you prefer, but stick to one. I recommend you just use yarn since your readme only references yarn.
I could see that you had used npm and yarn, since you had both package.lock and yarn.lock files in your repo. I can't tell you exactly what the issue was, but it must've been the interaction between having npm installed packages and yarn installed packages causing the mismatched version. It might've been the missing dependency too. :)
you're very welcome!
I was thinking react-router-dom is included in react-dom. Your input please.
when I tried to do
yarn starton your project, I kept getting errors to do with react-router-dom being missing. You may have added this with npm without the--saveflag. without it, it won't be added to your package.json but still installed in node_modules.yarn addwill do this automatically.p.s. my dev.to handle is @jenbutondevto :)
okay @jenbutondevto thank you very much
WOOOOOOOOOW!!! IT WORKED
I AM SO HAPPY! I had to put it aside, but after doing what you said everything is working great.
I removed: node_modules, package.lock, yarn.lock.
and installed react-router-dom
and it just great.
THANKS SO SO MUCH @jen ! I AM REALLY GRATEFUL.
When I remove the useHistory hook,
console.log(window.React1 === window.React2); returns TRUE
But, when I add it
console.log(window.React1 === window.React2); returns FALSE
