I'm new in graphql. I try to add entity manger in my resolver using injecting service in constructor

class Characters
{
	public $em;
	public function __construct(EntityManagerInterface $em)
	{
		$this->em = $em;
	}
 public function getHumans()
 {
 dd($this);
 $humans = self::findByType(self::TYPE_HUMAN);
 
 return $humans;
 }
}

but when i query this. I always get this error Using $this when not in object context. May i know how can I fix this issue?

App\Resolver\Characters:
 arguments: ['@doctrine.orm.entity_manager']

You should declare your service as a resolver. You can see how this can be done here.
