Cannot find module '@prisma/client/runtime/query_compiler_bg.postgresql.wasm'

Hi,

I keep getting this very annoying issue that only occurs when I push to Vercel, but not locally. I get:

2025-08-08T16:06:07.964Z [error] # SERVER_ERROR:  Error [PrismaClientKnownRequestError]: 
Invalid `prisma.user.findFirst()` invocation:

I've tried all the fixes on https://github.com/prisma/prisma/issues/25833 to no avail. Help would be much appreciated as my app is currently broken right now and I have no idea how to fix it.

Also a separate question, when generating the Prisma client to a customer folder, should I gitignore it because it will build when being deployed anyway? Thanks in advance.
