Create operation does not accept undefined value

[iksemot]

Description and expected behavior

Method create errors because of undefined as the value of relation.

The workaround is to use {} but undefined is valid and allowed in pure PrismaClient.

Environment (please complete the following information):

• ZenStack version: 1.0.2
• Prisma version: 5.4.2
• Database type: sqlite, postgres

Additional context

Given data model:

// 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"
}

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

model User {
  id    Int     @id @default(autoincrement())
  name  String

  post   Post? @relation(fields: [postId], references: [id])
  postId Int?

  @@allow('all', true)
}

model Post {
  id    Int    @id @default(autoincrement())
  title String
  User  User[]

  @@allow('all', true)
}

Following code:

const prisma = enhance(new PrismaClient(), {})
    
const user = await prisma.user.create({
  data: {
    name: 'Me',
    post: undefined
  }
})

Errors with:

I have a similar issue (if not the same), but just in case it can help :

// 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"
}

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

model User {
  id  String     @id @default(autoincrement())
  name  String

  createdPosts  Post[] @relation("CreatedPosts")

  @@allow('all', true)
}

model Post {
  id    Int    @id @default(autoincrement())
  title String
  createdBy String?

  creator  User?  @relation("CreatedPosts", fields: [createdBy], references: [id], onDelete: Cascade)

  @@allow('all', true)
}

Following code:

const prisma = enhance(new PrismaClient(), {})
    
const post = await prisma.post.create({
  data: {
    title: 'Title',
    creator: {
          connect: {
            id: undefined,
          },
        },
  }
})

Errors with:

Argument `connect` of type UserWhereUniqueInput needs at least one of `id` or `email` arguments. Available options are marked with ?.
