GraphQLError [Object]: Type MoodCount must define one or more fields.

[omarkhatibco]

Hi,

I think I found a bug, I'm not sure but this bug is related to a preview feature selectRelationCount.

I think this related to #26.

so I got this error in Terminal.

the problem is here

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

  // Data
  name String

  //Extras
  /// @HideField({  input: true })
  createdAt DateTime @default(now())
  /// @HideField({  input: true })
  updatedAt DateTime @updatedAt

  /// @HideField({ output: true, input: true })
  author   User?   @relation(fields: [authorId], references: [id])
  authorId String?

  // connection to mood
  /// @HideField({ output: true, input: true })
  posts Post[]
}

Because posts are hidden in both output and input, it geerate this following type.

import { Field } from '@nestjs/graphql';
import { ObjectType } from '@nestjs/graphql';
import { Int } from '@nestjs/graphql';
import { HideField } from '@nestjs/graphql';

@ObjectType()
export class MoodCount {
    @HideField()
    posts!: number;
}

Thanks for bug report. Interesting case. I'm still thinking how to deal with that...
Probably @HideField({ output: true }) should not affect on fields in aggregate output types
