CLI doesn't register object union with null

[adamghowiba]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Using a union type with null. IE string | null

Minimum reproduction code

NA

Steps to reproduce

No response

Expected behavior

Using the GraphQL CLI, set an object property to a union containing null

import { User} from '@prisma/client';


@ObjectType()
export class UserEntity implements User {
  @Field(() => ID)
  id!: number;

  first_name!: string;

  middle_name!: string | null; // <-- Will not set the output object to be nullable. 
  
  // Setting middle_name to undefined will throw a type error
  // because prisma will always return null for undefined fields
}

After looking again I saw #1072 spoke about this back in 2020, any chance we'd be willing to revisit this? ☹️ @kamilmysliwiec

If all else fails, is there any easy way to fork the NestJS GraphQL CLI to accommodate null unions?
