Just started this project, used create-next-app@latest and installed prisma, nextauth and prisma adapter according to latest docs. DB is properly configured and tested, next secret is set, middleware.ts, auth.ts, and prisma.ts copied from official docs, Google oauth creds are set correctly. Here is the error output

Runtime Error

Downgrading to @auth/prisma-adapter 2.7.2 should solve it. There is an open issue for this, see https://github/nextauthjs/next-auth/issues/12731
