Hi Guys I am building a full-stack application using turbo-repo. Soo my backend is using serverless AWS and I have a shared database folder which I import from. When using the query system I had to set an env variable: PRISMA_QUERY_ENGINE_LIBRARY to tell pull the generated stuff from the right place. This has caused a lot of issues around the lambda sizes being massive! Soo I found the new way of using the query_compiler_bg.wasm. But I have the same issue where it is not pointing to the right generated folder as it in in a separate folder.

soo where it is trying to find it from here:

/Users/work/repos/project/services/employer/src/generated/prisma/query_compiler_bg.wasm

it is actually meant to find it from here:

/Users/work/repos/project/services/employer/node_modules/@relay/database/src/generated/prisma/query_compiler_bg.wasm.

I got this working for the library query engine because I just set the path:

/var/task/node_modules/@relay/database/src/generated/prisma/libquery_engine-rhel-openssl-1.0.x.so.node

You chose to debug with a human. They'll tinker with your query soon. If you get curious meanwhile, hop into #ask-ai for a quick spin!

I figured out the problem and I think Iknow what the solution is. We have a turbo repo:

root
-- services:
---- employer:
------ node_modules:
--------@root/database/src/generated/prisma/query_compiler_bg.wasn

-- packages
---- Database:
------ client and all the other good stuff such as schema and etc

The schema is as shows:

generator client {
provider = "prisma-client-js"
output = "../generated/prisma"
engineType = "client"
}

it fails because when the backend service tries to get this client and generated types from the dependcy which is located in the turborepo packages/databases. It tries to find the query_compiler_bg.wasm in the wrong location:

/Users/work/repos/project/services/employer/node_modules/@relay/database/src/generated/prisma/query_compiler_bg.wasm.

whereas it should be:
/var/task/node_modules/@relay/database/src/generated/prisma/libquery_engine-rhel-openssl-1.0.x.so.node

is there a way we can override the path the same way we can with the library query engine:
PRISMA_QUERY_ENGINE_LIBRARY

Try this generator instead

generator client {
 provider = "prisma-client"
 output = "./generated"
 engineType = "client"
}

#

Use ./generated/client to import the prisma client

@copper pond This generator is causing issues, because we are using serverless AWS and I don't know if that is causing issues:
