Affichage symfony

Bonjour , j'ai un problème au niveau de l'affichage de mes données j'explique j'ai fait un crud d'une entity sauf que cette entitty a une relation avec une autre ce qui quand je veux par exemple edit la page m'affiche error can't convert to string comme l'attribut relationnel est un tableau mais je ne sais pas comment faire pour que il ne le soit plus ou qu'il le reste mais que je l'affiche sans problème

Mon controller :
 

<?php

namespace App\Controller;

use App\Entity\User;
use App\Form\UserType;
use App\Repository\UserRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

#[Route('/user')]
class UserController extends AbstractController
{
    #[Route('/', name: 'app_user_index', methods: ['GET'])]
    public function index(UserRepository $userRepository): Response
    {
        return $this->render('user/index.html.twig', [
            'users' => $userRepository->findAll(),
        ]);
    }

    #[Route('/new', name: 'app_user_new', methods: ['GET', 'POST'])]
    public function new(Request $request, EntityManagerInterface $entityManager): Response
    {
        $user = new User();
        $form = $this->createForm(UserType::class, $user);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $entityManager->persist($user);
            $entityManager->flush();

            return $this->redirectToRoute('app_user_index', [], Response::HTTP_SEE_OTHER);
        }

        return $this->renderForm('user/new.html.twig', [
            'user' => $user,
            'form' => $form,
        ]);
    }

    #[Route('/{id}', name: 'app_user_show', methods: ['GET'])]
    public function show(User $user): Response
    {
        return $this->render('user/show.html.twig', [
            'user' => $user,
        ]);
    }

    #[Route('/{id}/edit', name: 'app_user_edit', methods: ['GET', 'POST'])]
    public function edit(Request $request, User $user, EntityManagerInterface $entityManager): Response
    {
        $form = $this->createForm(UserType::class, $user);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $entityManager->flush();

            return $this->redirectToRoute('app_user_index', [], Response::HTTP_SEE_OTHER);
        }

        return $this->renderForm('user/edit.html.twig', [
            'user' => $user,
            'form' => $form,
        ]);
    }

    #[Route('/{id}', name: 'app_user_delete', methods: ['POST'])]
    public function delete(Request $request, User $user, EntityManagerInterface $entityManager): Response
    {
        if ($this->isCsrfTokenValid('delete'.$user->getId(), $request->request->get('_token'))) {
            $entityManager->remove($user);
            $entityManager->flush();
        }

        return $this->redirectToRoute('app_user_index', [], Response::HTTP_SEE_OTHER);
    }
}

Mon Form :
 

<?php

namespace App\Form;

use App\Entity\User;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class UserType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('email')
            ->add('roles')
            ->add('password')
            ->add('isVerified')
            ->add('nom')
            ->add('prenom')
            ->add('telephone')
            ->add('adresse')
            ->add('idVille')
        ;
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => User::class,
        ]);
    }
}
