Cannot find name '$PrismaModel' due to feature extendedWhereUnique with preview feature fieldReference

[haimprecise]

Bug description

Using the following ref:

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["fieldReference", "extendedWhereUnique"]
}

With Prisma versions 4.5+ yields:
node_modules/.prisma/client/index.d.ts:20937:43 - error TS2304: Cannot find name '$PrismaModel'.
across the entire index.d.ts file

However, when either fieldReference or extendedWhereUnique are removed, the file compiles properly.

We cannot use both fieldReference and extendedWhereUnique but our code heavily relies on them.

How to reproduce

Expected behavior

Should properly compile

Prisma information

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["fieldReference", "extendedWhereUnique"]
}

Environment & setup

same problem

I have narrowed it down.

It works when I remove extendedWhereUnique. Somehow they are colliding.

@haimprecise @VasiliyIsaichkin Could you provide an example schema to reproduce this?
Does it error when running tsc --noEmit?

[haimprecise]

This an example:

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["extendedWhereUnique", "fieldReference"]
}

model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
}

typescript: 4.7.4
prisma: 4.6.1
@client/prisma: 4.6.1

Happens for tsc --noEmit

[haimprecise]

Is this issue being reviewed by some team member?

In summary, fieldReference collides with extendedWhereUnique. Both features are gold for us!

Same issue with
typescript: 4.9.5
prisma: 4.10.1

[haimprecise]

As a feedback for Preview features, fieldReference and extendedWhereUnique aren't working together.

typescript: 4.9.5
prisma: 4.13.0

[aqrln]

I can reproduce with latest Prisma, some types are missing the $PrismaModel generic type parameter on the type declaration although they use it in their fields, e.g:

  /**
   * User base type for findUnique actions
   */
  export type UserFindUniqueArgsBase = {
    /**
     * Select specific fields to fetch from the User
     */
    select?: UserSelect | null
    /**
     * Filter, which User to fetch.
     */
    where: UserWhereUniqueInput<$PrismaModel>
  }

Note that you need skipLibCheck: false in your tsconfig to see the compiler error.
