Bug description

When trying to build prisma-using project with TS 4.8, following errors are thrown:

How to reproduce

Try running tsc on a Prisma project with TypeScript 4.8

Expected behavior

tsc successfully compiles project

Prisma information

Schema:

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

generator client {
  provider = "prisma-client-js"

Repository:

import type { PrismaClient, User } from '@prisma/client'

export type CreateUserRow = Omit<User, 'id'>

export class UserRepository {
  private readonly prisma: PrismaClient

  constructor(prisma: PrismaClient) {
    this.prisma = prisma
  }

  async getUser(id: number): Promise<User | null> {
    const user = await this.prisma.user.findUnique({
      where: {
        id,
      },
    })

    return user
  }

  async createUser(user: CreateUserRow): Promise<User> {
    const createdUser = await this.prisma.user.create({
      data: user,
    })
    return createdUser
  }
}

Environment & setup

TypeScript 4.8.2

Prisma Version

Prisma 4.2.1

I have the same issue, and same errors from TS.

For now, the only way I found to temporarily circumvent this was to use tsc-silent

"build": "tsc-silent --suppress @node_modules/.prisma/",

Downgrading TS to 4.7.4 and it will compile.

Hi!
So we have a PR almost ready to be merged, it didn't make it to the 4.3.0 release yesterday.
We'll keep you updated when it's solved and in which version 👍🏼
In the meantime, keep TS < 4.8.
