Serialized Object to JsonResponse return empty response using serializer service in Symfony 5 Controller

Question

I use to add vue3 frontend content in a backend symfony 5, I need to return a jsonResponse for sorting values in the front, I did a Serializer Service to Serialize in Json an object which is from the Doctrine Repository, The BDD callback is a type Grilles object, So to have a Json from the object I use for Serializer, Until that there's no problem, The Serializer service return correct Object but it's empty about the content... I don't see anything about that, can you debugging me please ?

The SerializerService:

namespace App\Services;

use Symfony\Component\Serializer\Encoder\JsonEncoder;
use Symfony\Component\Serializer\Encoder\XmlEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Serializer;

class SerializerService
{
    public function serialize()
    {

    $encoders = [new XmlEncoder(), new JsonEncoder()];
    $normalizers = [new ObjectNormalizer()];

    $serializer = new Serializer($normalizers, $encoders);

    return $serializer;
    
    }
}

The Repository:

public function findOneInAllGrillesObj($email, $type): ?Grilles
    {
        return $this->createQueryBuilder('g')
            ->andWhere('g.email = :email')
            ->andWhere('g.type = :type')
            ->setParameter('email', $email)
            ->setParameter('type', $type)
            ->getQuery()
            ->getOneOrNullResult()
        ;
    }

The controller:

/**
     *
     * @Route("/grilleADisplay", name= "grilleADisplay", methods={"GET","POST"})
     * IsGranted("ROLE_USER", message="vous devez vous connecter pour accéder à cette ressource")
     */
    public function jsonDisplayGrilleA(EntityManagerInterface $manager, SerializerService $serializer): JsonResponse
    {
        if(is_null($this->getUser())){
            $session=$request->getSession();
            $session->getFlashBag()->add("messageError" , "Vous devez être connecté pour accéder à cette ressource");
            return $this->redirectToRoute("login");
        }
        $type="A";
        $email=$this->getUser();
        $em = $this->getDoctrine()->getManager();
        $grillesrepository = $em->getRepository(Grilles::class);
        $datas = $grillesrepository->findOneInAllGrillesObj($email, $type);
        //dd($datas);
        $jsonContent = $serializer->serialize($datas);
        //dd($jsonContent);
        dd(new JsonResponse($jsonContent));
        return new JsonResponse($jsonContent);
    }

The DD give:

Ok that's fine I know how to ! The serializer is not the answer about have a not empty return, Like I see in Symfony 4 - JsonResponse returns a non-empty object as empty The object Grilles must be transform in array by:

$datas=(array)$datas;

Before return like that a JsonResponse:

 $datas = new JsonResponse($datas);

I add this, if the repository return an array it don't work, must return an object ans convert to an array before return new JsonResponse() (Symfony 5)
