What do you mean here?
This looks like you may have an empty page file. Without a repository or some screenshots of the project is gonna be hard to guess. |

There is no code in app—all code is in app and components.

Aha, you'd need to upload them to the Github discussion thread. If it is private or sensitive information DO NOT share it. Not sure what the issue could be though - maybe move the project into a sub folder? |

Not sure what the issue could be though - maybe move the project into a
sub folder? C:/my-apps/ws-ui-new-fresh- not sure why that'd work, but
might as well try it. Otherwise I don't know.

Summary
Describe the bug After migrating all code to the new app and components directories and removing all legacy files, the Next.js static build fails with the following error:
Type error: File 'C:/ws-ui-new-fresh/src/app/page.js' is not a module.
There is no code in app—all code is in app and components.
I have tried:
Upgrading and downgrading Next.js
Cleaning .next and reinstalling dependencies
Creating placeholder files in app
Ensuring all imports and configs are correct
The validator still references old, deleted files and blocks the build.
Dev mode works fine; only static build is broken.
Expected behavior The build should succeed when all code is in the correct modern locations and no legacy files remain.
System info
Next.js version: 15.5.2 (also tried other recent versions)
Node.js version: [your version]
OS: Windows
Additional context This is blocking production deployment. Please advise or fix as soon as possible.
Copy and paste this into https://github.com/vercel/next.js/issues/new/choose (choose “Bug report”). Add your Node.js version if you can.
Let me know if you want to add or change anything!
