Throws "TypeError: Cannot read property 'args' of undefined" error when @ignore is present

[Borales]

Sample schema:

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

generator typegraphql {
  provider = "typegraphql-prisma"
}

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

model File {
  id      String @id @default(cuid())
  ownerId String @map("owner_id")

  owner User @relation("file_owner", fields: [ownerId], references: [id]) @ignore

  @@map("files")
}

model User {
  id String @id @default(cuid())

  uploadedFiles File[] @relation("file_owner")

  @@map("users")
}

When @ignore decorator is present (File model, owner relation) - typegraphql-prisma throws the following error:

I think that you use @ignore in a wrong way.
The purpose of that feature is to exclude invalid relations to invalid models.
If you put @ignore also on the other side of the relation, it works correctly.

@MichalLytek apologies, I probably posted not the best sample.

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

generator typegraphql {
  provider = "typegraphql-prisma"
}

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

model File {
  id      String @id @default(cuid())
  ownerId String @map("owner_id")

  owner  User  @relation("file_owner", fields: [ownerId], references: [id])
  posts   Post[] @relation("post_thumbnail") @ignore

  @@map("files")
}

model User {
  id String @id @default(cuid())

  uploadedFiles File[] @relation("file_owner")

  @@map("users")
}

model Post {
  id String @id @default(cuid())
  thumbnailId String

  thumbnail      File           @relation("post_thumbnail", fields: [thumbnailId], references: [id], onDelete: SetNull)
}

I want to be able to access Post.thumbnail, but I don't care about File.posts (and I don't want it to be generated by Prisma).

Anyway, seems like you fixed this on dev. Is there an ETA for this to be released?

[MichalLytek]

Today will be a new release, as always 😉
