PrismaClientInitializationError Prisma Client could no locate the Query Engine rhel-openssl-3.0.x

Good day Everyone,

I am currently working on a project. Where I utilize Prisma ORM with PrismaAppSync. At the moment I am simply trying to perform some prisma client queries (without AppSync) simply to test.

I continuously get this error while running my AWS Lambda 
Prisma Client could not locate the Query Engine for runtime \"rhel-openssl-3.0.x


I am using Amplify Gen2 (Typescript) to create my infrastructure as code. The prisma client is within a Lambda Layer. During the amplify build, I run a postinstall script 
npx prisma generate --schema=./prisma/schema.prisma
. Everything from the build gets redirected to the node_modules folder within my AWS Lambda Layer.

AWS Lambda & Layer Runtimes = Node 20
Database Amazon Aurora (MySQL) => connection has been established and was able to query the DB using mysql2

Within schema.prisma
datasource db {
  provider = "mysql"
  url      = env("DATABASE_URL")
}

generator client {
  provider      = "prisma-client-js"
  binaryTargets = ["native", "rhel-openssl-3.0.x"]
}

generator appsync {
  provider = "prisma-appsync"
  output   = "../node_modules/@prisma-appsync"
  binaryTargets = ["native", "rhel-openssl-3.0.x"]
}


When I download my Lambda layer locally. I do see the rhel-openssl-3.0.x binary files, I am not sure why prisma isn't able to locate it.

Any ideas?

I appreciate the help!

Thanks 🙂
