craco build fails after upgrading to react-scripts v5

[Nefcanto]

Hello

I'm using CRACO and everything worked fine, until two days ago I upgraded to react-scripts v5. Now the craco start works and I can develop, but the craco build fails with a vague message that only points to the entire src directory.

I checked my code, and no change is made that contains ....

Step 13/20 : RUN npm run build
 ---> Running in be63fc0279e8

> [email protected] build
> craco build

Creating an optimized production build...
Failed to compile.

Module not found: Error: Can't resolve '...' in '/Company/Project/src'


The command '/bin/sh -c npm run build' returned a non-zero code: 1

How can I debug this error?

I'm suffering from a different issue where Craco builds with an error match.loader.options.plugins is not a function. This is related to the upgrade of Webpack with the newest CRA release. Not sure what to do yet though.

If you're using Tailwind, upgrade to version 3 and remove its config from CRACO. That worked for me.

Thanks. No, I'm using various Webpack plugins that need to be added - Craco is still meant specifically for Webpack 4, I guess.
