[symfony 5]Neither the property ...existe

Bonjour,

Voila je rencontre un petit problème avec mon code.

ceci le code d'erreur :
Neither the property "callcenterId" nor one of the methods "callcenterId()", "getcallcenterId()"/"iscallcenterId()"/"hascallcenterId()" or "__call()" exist and have public access in class "Symfony\Component\Form\FormView".

mon controlleur :

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use App\Entity\VicidialUserGroups;
use App\Entity\CallCenterGroups;
use App\Entity\CallCenter;
use App\Form\VicidialUserGroupsType;
use App\Form\CallCenterGroupsType;

class GroupeController extends AbstractController
{
    public function nouveauAction(Request $request): Response
    {
        $session = $request->getSession();
        if ($session->get('niveau') !== 4){
           throw $this->createAccessDeniedException();
        }    
        $groupe = new VicidialUserGroups();
        $cappelgrp = new CallCenterGroups();

        $form = $this->createForm(VicidialUserGroupsType::class, $groupe);
        $form_assignment = $this->createForm(CallCenterGroupsType::class, $cappelgrp);

        $em = $this->getDoctrine()->getManager();
        $form->handleRequest($request);
        $form_assignment->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()  || $form_assignment->isSubmitted() && $form_assignment->isValid){
        $centreappel = $em->getRepository(CallCenter::class)->find($form->get('callcenterId')->getData());  
        $cappelgrp->setUserGroup($centreappel->getTriptyque() . '_' . $form->get('userGroup')->getData());
        $groupe->setUserGroup($centreappel->getTriptyque() . '_' . $groupe->getUserGroup());
        $groupe->setGroupName($centreappel->getTriptyque() . '_' . $groupe->getGroupName()); 
        $em->persist($groupe); 
        $em->persist($cappelgrp);
        $em->flush();

        }

        return $this->render('groupe/nouveau_groupe.html.twig', array('form' => $form->createView()   , 'form_assignment' =>$form->createView() ));
    }
}

Mon entitéCallCenterGroups:

<?php

    private $id;

    */
    private $userGroup;

  /**

    */
    private $callcenterId;

  public function getId(): ?int
  {
  return $this->id;
  }

  public function getUserGroup(): ?string
  {
  return $this->userGroup;
  }

  public function setUserGroup(string $userGroup): self
  {
  $this->userGroup = $userGroup;

  return $this;

  }
  /**

  • Set callcenterId
  • @param integer callcenterId

  • @return CallCenterGroups
    */
    public function setCallcenterId($callcenterId) {
    $this->callcenterId = $callcenterId;

    return $this;
    }

  /**

  • Get callcenterId
  • @return integer
    */
    public function getCallcenterId() {
    return $this->callcenterId;
    }

}

mon formulaire :

<?php
