One of your dependencies (node_modules) imports a CSS Modules file.

This normally happens when a package's source files are accidentally consumed, instead of the built package.

Reach out to the maintainer and ask for them to publish a compiled version of their dependency.

Compiled dependencies do not have references to CSS Module files, or any other files that require bundler-specific integrations.

The dependency should also provide instructions about what CSS needs to be imported by you, in your application.

If this is first-party code, try including monorepo packages in the compilation pipeline.

Good to know: This limitation does not exist when using the app directory.
