CannotDetermineGraphQLTypeError

[ImperatorOfIntellectualism]

Describe the Bug
Cannot determine GraphQL output type for 'Posts' of 'Thread' class. Is the value, that is used as its TS type or explicit type, decorated with a proper decorator or is it a proper output value?

To Reproduce

import { Entity, PrimaryKey, Property } from "@mikro-orm/core";
import { Field, Int, ObjectType } from "type-graphql";

@ObjectType()
@Entity()
export class Thread {
@Field(()=> Int)
  @PrimaryKey()
  id!: number;

  @Field(()=> String)
  @Property({type: 'date'})
  createdAt = new Date();

  @Field(()=> String)
  @Property({type: 'text'})
  title!: string;

  @Field(()=> String)
  @Property({type: 'text'})
  OP!: string;

  @Field(()=> Array)
  @Property()
  Posts!: number[];
}

Expected Behavior
It should work without the error
