Details

I try to migrate from webpack to rspack, when I start dev server got this error,however I already config '.tsx' in resolve.extensions.
Found module './src/index.tsx'. However, it's not possible to request this module without the extension
if its extension was not listed in the resolve.extensions. Here're some possible solutions:
1. add the extension ".tsx" to resolve.extensions in your rspack configuration
2. use './src/index.tsx' instead of './src'

Reproduce Steps

I try to migrate from webpack to rspack, when i start dev server got this error:
Found module './src/index.tsx'. However, it's not possible to request this module without the extension if its extension was not listed in the resolve.extensions. Here're some possible solutions: 1. add the extension ".tsx"toresolve.extensions in your rspack configuration 2. use './src/index.tsx' instead of './src'
but I already config '.tsx' in resolve.extensions,I dont know why this occur,how I can fix this?
This is my config:
