Issue with basePath and Server Actions on client components

[migueldamota]

Link to the code that reproduces this issue

https://github.com/migueldamota/nextjs-basepath-issue

To Reproduce

1. Start app with bun dev --turbo
2. Go to page (http://localhost:3000/any-path)
3. Check console for Failed to get source map: Error: Failed to read file contents of... error message

Current vs. Expected behavior

I would expect to not have an error, so that the basePath is removed from the requested file, ignored or trimmed

Additional context

This is only happening when using "use client", when it's removed no error is being logged.
