Module not found error

Hi, I installed and am trying to use in my create-react-app but I'm getting this error. Any ideas?

This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
	- add a fallback 'resolve.fallback: { "assert": require.resolve("assert/") }'
	- install 'assert'
If you don't want to include a polyfill, you can use an empty module like this:
	resolve.fallback: { "assert": false }

Hi 👋
Looks like create react app uses webpack 5 which have beeaking changes for some of used Solana modules.
The only quick fix would be to use Webpack 4. But Im not sure how to enable it with CRA.
I will check tomorrow if I can fix it and deploy update. Thank you for reporting!

Similar issue on anza-xyz/wallet-adapter#241

For those who have such error with webpack follow advice in issue above using other tools than CRA and webpack 5.

One of the tool I made and use myself: React.JS/ Next.JS
