AWS Lambda: @prisma/client did not initialize yet. Please run \"prisma generate\" and try to import it again.

Bug description

I'm trying to configure Prisma on our backend to replace typeorm. It works fine locally, but when i deploy it, i have the following error: @prisma/client did not initialize yet. Please run "prisma generate" and try to import it again.
I've listed directory content, and i can see that libquery_engine-rhel-openssl-1.0.x.so.node and schema.prisma are present in ./node_modules/.prisma/client. I'm lost here, and we are about to cancel the migration to Prisma.

Anyone has an idea of what could cause this error ?

How to reproduce

1. push repository to github to trigger deployment via circle ci
2. install:

npm ci
npx prisma generate

3. deploy:

npx serverless deploy --stage develoment

4. init Prisma client with the following config:

new PrismaClient({
        log: ['info', 'warn', 'error'],
        datasources: {
          db: {
            url: postgres://login:password@foo.bar.us-east-1.rds.amazonaws.com:5432/mydatabase_development?timezone=UTC,
          },
        },
      })

and get this:

    "error": {
            "stack": "Error: @prisma/client did not initialize yet. Please run \"prisma generate\" and try to import it again.\nIn case this error is unexpected for you, please report it in https://pris.ly/prisma-prisma-bug-report\n    at new PrismaClient (/var/task/node_modules/.prisma/client/default.js:43:11)\n    at Function.getInstance (webpack://ramdam-front-exposition-api/src/database/prisma/client.ts:11:34)\n    at getPrismaClient (webpack://ramdam-front-exposition-api/src/database/prisma/client.ts:24:54)\n    at <anonymous> (webpack://ramdam-front-exposition-api/src/api/users/controllers/get-me.ts:35:35)\n    at Generator.next (<anonymous>)\n    at fulfilled (webpack://ramdam-front-exposition-api/src/api/users/controllers/delete-me.ts:20:2)\n    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"

Expected behavior

prisma to be intialized

Hi @coulonxyz 👋

Thank you for raising this question.

Are you following this guide to deploy to AWS Lambda? Did you include the prisma generate script in the serverless.yml file?
