But it is working on local machine.

Then I try to move app to root, the Error is still:

Expected Behavior

Should NOT output Error: Cannot find module 'redux'

To Reproduce

Deploy https://github.com/crossjs/cofe/tree/main on Vercel

[controversial]

I have a similar error, also using workspaces, and also only appearing on Vercel. However, I was able to get vercel-specific errors like this without using workspaces as well.

Hi, this is being investigated, can you try adding outputFileTracing: false to your next.config.js?

[vvenv]

After adding outputFileTracing: false to next.config.js, it works.
Thanks.
