prisma: Error: @prisma/client did not initialize yet. Please run "prisma generate" and try to import it again. with Nexus

Bug description

I had an old project (~6 months old) which I tried converting to Prisma as of the official release but got a weird bug so I stopped it. Now I updated dependencies again to use aggregation (v2.2.0) & now got this error (I used DEBUG=* flag):

~/server is the folder name 😃

How to reproduce

Idk

Expected behavior

It should work as it used to. My changes from old nexus with new nexus are perfect.
