Field defined in resolvers, but not in schema when using class as return value

[zuffik]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Given this code and assuming everything else is set up correctly (I can provide Graphql module config if necessary)

import {
  Field,
  Int,
  ObjectType,
  Query,
  ResolveField,
  Resolver,
} from '@nestjs/graphql';

const getDto = () => {
  @ObjectType({ isAbstract: true })
  abstract class Dto {
    @Field(() => Int)
    id: number = 1;
  }
  return Dto;
};

@ObjectType()
export class Child extends getDto() {}

const getDynamicResolver = () => {
  @Resolver(getDto(), { isAbstract: true })
  abstract class DynamicResolver {
    @Query(() => Child)
    dto() {
      return new Child();
    }
    @Query(() => Child)
    setDto() {
      return new Child();
    }

    //@ResolveField(() => String)
    //helloWorld() {
    //  return 'foo';
    // }
  }

  return DynamicResolver;
};

@Resolver(Child)
export class DynamicResolver extends getDynamicResolver() {}

I get this error: Error: Child.helloWorld defined in resolvers, but not in schema. Everything else works fine (queries and mutations are executed as expected) and everything is present in schema.

Workaround

One of the options is to set @Field to entity that is defined in @Resolver argument but in this way I'm not able to use @Args.

Minimum reproduction code

https://github.com/zuffik/nestjs-schema-problem-repo/tree/main/src

Steps to reproduce

1. install dependencies (yarn)
2. start project (yarn start:dev)

Expected behavior

I expect the application is able to recognize fields in any context.
