Nestjs @prisma/client did not initialize yet. Please run "prisma generate" and try to import it again

I am using pnpm [email protected] and Prisma 6.19.0 for a backend application. When I add the Prisma service, I get the error

 Nest] 46276  - 17/11/2025, 12:45:49   ERROR [ExceptionHandler] Error: @prisma/client did not initialize yet. Please run "prisma generate" and try to import it again.

I have run pnpx prisma generate. This returns Generated Prisma Client (6.19.0) to ./generated/prisma

Based on the NestJs site, I have updated tsconfig.build.json to have the entry:

"include": ["src", "generated"],

In schema.prisma I have:

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

In the prisma.service.ts I have:

import { Injectable, OnModuleInit } from '@nestjs/common';
import { PrismaClient } from '@prisma/client';

@Injectable()
export class PrismaService extends PrismaClient     implements OnModuleInit {
  async onModuleInit() {
  await this.$connect();
 }
}

If it would help, I can add the project to GitHub.

I am unclear how to correct the error
