Prisma & Yarn2

[adarnon]

Bug description

I can't import @prisma/client using yarn2. I'm getting an ambiguous dependency error.
My app is a Next.js backend server, but I don't think that's relevant.
Looks like the problem is that the main @prisma/client file imports .prisma/client (which is my generated client), but it is not declared as a dependency. Tried some packageExtension hacks in .yarnrc.yml but couldn't get it to work.

Error message:

Error: @prisma/client tried to access .prisma, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Required package: .prisma (via ".prisma/client")
Required by: @prisma/client@virtual:a83299fcd4deff07af72855eb207a7bfe60d62cd7bb2fc25e687e90d98445922cc96eb8ad550ce887958d6785d66a29c22e8989a690cc567c0750803784c6d26#npm:2.3.0 (via /Users/***/.yarn/unplugged/@prisma-client-virtual-9903ad0e60/node_modules/@prisma/client/)
