I’ve tried solving this for days now and please need your expertise.
My codebase is a turborepo monorepo with web apps under /apps/… and database packages used by those apps under /packages/… (pretty standard)
The generator client code in the /packages/db1/prisma/schema.prisma is:
generator client {
provider = “prisma-client-js”
output = “../generated/client”
binaryTargets = [“native”, “rhel-openssl-3.0.x”]
}
Everything installs and builds correctly on my local, however on Vercel I keep getting this error with any db operation:
Unhandled Rejection: Error [PrismaClientInitializationError]: 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 “generated/client”.We would appreciate if you could take the time to share some information with us.
