I\'ve been trying to call Entity Manager in a constructor:

function __construct()

    $this->getDoctrine()->getEntityManager();
    ...

Don't extend the base controller class when you register controller as a service. There is a documentation about it here

class ImageTestController
{
     private $em;

     public function __construct(EntityManager $em)
     {
         $this->em = $em;
     }

     public function someAction()
     {
         // do something with $this->em
     }
}

// services.yml
services:
    acme.controller.image_test:
        class: Acme\SomeBundle\Controller\ImageTestController

// routing.yml
acme:
    path: /
    defaults: { _controller: acme.controller.image_test:someAction }
