réponse d'affichage de bogue avec fosrestBundle

Question

J'ai utilisé fosrestBundle pour api mais j'ai un bug quand j'invoque des données pour la base de données. ceci est une erreur:

An instance of Symfony\Bundle\FrameworkBundle\Templating\EngineInterface must be injected in FOS\RestBundle\View\ViewHandler to render templates.

Code AppController.php:

<?php 

    namespace Med\MedBundle\Controller; 

    use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 
    use Symfony\Component\HttpFoundation\Request; 
    use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
    use FOS\RestBundle\Controller\Annotations\RouteResource; 
    use FOS\RestBundle\Controller\Annotations\View; 
    use Med\MedBundle\Entity\Med; 
    use Symfony\Component\HttpFoundation\JsonResponse; 
    /** 
    * @RouteResource("usse") 
    */ 

    Class AppController extends Controller { 

    public function getAction() { 
      $em = $this->getDoctrine()->getManager(); 
      $test = $em->getRepository('MedMedBundle:Med')->findAll(); 
      return array('test'=>$test); 
     } 

    } 

Code config.yml:

imports: 
     - { resource: parameters.yml } 
     - { resource: security.yml } 
     - { resource: services.yml } 

    # Put parameters here that don't need to change on each machine where the app is deployed
