When using injection independence in any resolver not working, example 

```typescript
@Resolver()
export class UserResolver {
  constructor(private userService: UserService) {}

  @Query(() => [UserModelGQL])
  async getUsers(): Promise<UserModelGQL[]> {
    return await this.userService.getAll();
  }
}
```

this.userService is null !!!
