Describe the Bug

When running next build on vercel the following error is thrown:

20:22:28.588 | Error: Cannot find module 'next/dist/next-server/server/next-server'

It doesn't happen locally. I have disabled the build cache and ran a deployment multiple times. Could be related to #26734

Expected Behavior

The build should succeed.
