vercel Prisma Client could not locate the Query Engine

Hey, I'm currently trying to deploy the development version of my website on vercel and I have started getting this error after updating to version 6.4.1 (previously was on 5.4). 
Prisma Client could not locate the Query Engine for runtime "rhel-openssl-3.0.x".

We detected that you are using Next.js, learn how to fix this: https://pris.ly/d/engine-not-found-nextjs.

This is likely caused by a bundler that has not copied "libquery_engine-rhel-openssl-3.0.x.so.node" next to the resulting bundle.
Ensure that "libquery_engine-rhel-openssl-3.0.x.so.node" has been copied next to the bundle or in "../../node_modules/.pnpm/@[email protected][email protected][email protected][email protected]/node_modules/.prisma/client".

We would appreciate if you could take the time to share some information with us.

I have read the guide linked in the error, but I am a little confused about some of the implementation for some of the "fixes". I have already implemented a globalForPrisma variable, only difference is I am using prisma in a monorepo, so I have a package called "database", which allows me to reuse my schema across all apps. This is not a build error, this is a runtime error and the prisma client is generated at build time using a npm script: "build": "pnpm run db:generate & tsup" as suggested in the guide above (at build time it is having no issues finding prisma schema)

Does the error go away if you downgrade to version 5.4? Did you try adding binaryTargets to your schema file? 
generator client {
  provider      = "prisma-client-js"
  binaryTargets = ["native", "rhel-openssl-3.0.x"]
}
generator client {
  provider      = "prisma-client-js"
  binaryTargets = ["native", "rhel-openssl-3.0.x"]
}

hi, i ended up downgrading to 5.4 again and it started working. However, I have just installed the latest version again and it all seems to be working fine? a bit confused, but ill take it as a win. I have not added any binary targets or packages as suggested above. im very happy to see the strictUndefinedChecks preview feature in v6 🙂
