Link to the code that reproduces this issue

https://github.com/tarungunampalli-rox/turbopack-imports-repro

To Reproduce

  1. Add imports field to package.json
  "imports": {
    "#/*": "./src/*"
  },
  1. Import some internal src file starting with the # subpath alias
  2. run build with turbopack

Current vs. Expected behavior

Logs from the reproduction show

Error: Turbopack build failed with 2 errors:
./src/app
Module not found: Can't resolve '#/greeting'
https://nextjs.org/docs/messages/module-not-found
./src/app/page.tsx:1:1
Module not found: Can't resolve '#/greeting'

I expect turbopack should be able to resolve internal imports using the #/ subpath alias
