Constraint is not taken in consideration - php

Question

I am doing a crud for an entity in my application. The form have to upload a file, so i added the assert in the entity file. But when i submit my form the validator give me an error and said to me that the field image have to be a string. I've done upload of file a hundred times, that why i don't understand this time why the validator bundles react like that.
My entity:
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity(repositoryClass="App\Repository\AlgorithmeRepository")
*/
class Algorithme
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=255)
*/
private $titre;
/**
* #ORM\Column(type="date")
*/
private $dateCreationArticle;
/**
* #ORM\Column(type="string", length=255, nullable=true)
*
* #Assert\File(mimeTypes={ "image/jpeg","image/png"})
*/
private $image;
/**
* #ORM\Column(type="array")
*/
private $analyse = [];
public function getId(): ?int
{
return $this->id;
}
public function getTitre(): ?string
{
return $this->titre;
}
public function setTitre(string $titre): self
{
$this->titre = $titre;
return $this;
}
public function getDateCreationArticle(): ?\DateTimeInterface
{
return $this->dateCreationArticle;
}
public function setDateCreationArticle(\DateTimeInterface $dateCreationArticle): self
{
$this->dateCreationArticle = $dateCreationArticle;
return $this;
}
public function getImage()
{
return $this->image;
}
public function setImage($image)
{
$this->image = $image;
return $this;
}
public function getAnalyse(): ?array
{
return $this->analyse;
}
public function setAnalyse(array $analyse): self
{
$this->analyse = $analyse;
return $this;
}
}
The form :
<?php
namespace App\Form;
use App\Entity\Algorithme;
use Symfony\Component\Form\Extension\Core\Type\DateType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class AlgorithmeType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('titre')
->add('dateCreationArticle',DateType::class,[
'widget' => 'single_text',
// prevents rendering it as type="date", to avoid HTML5 date pickers
'html5' => false,
// adds a class that can be selected in JavaScript
'attr' => ['class' => 'js-datepicker'],
])
->add('image',FileType::class,[
'required' => false,
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Algorithme::class,
]);
}
}
And the controller:
<?php
namespace App\Controller;
use App\Entity\Algorithme;
use App\Form\AlgorithmeType;
use App\Repository\AlgorithmeRepository;
use App\Services\CreateFormForArray;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
/**
* #Route("/algorithme")
*/
class AlgorithmeController extends AbstractController
{
/**
* #Route("/new", name="algorithme_new", methods={"GET","POST"})
*/
public function new(Request $request): Response
{
$algorithme = new Algorithme();
$form = $this->createForm(AlgorithmeType::class, $algorithme);
$form->handleRequest($request);
// die();
if ($form->isSubmitted() && $form->isValid()) {
$entityManager = $this->getDoctrine()->getManager();
$CreateFormForArray = new CreateFormForArray();
$CreateFormForArray->handleArrayString($request,$algorithme,"analyse");
$entityManager->persist($algorithme);
$entityManager->flush();
return $this->redirectToRoute('algorithme_index');
} else {
}
return $this->render('algorithme/new.html.twig', [
'algorithme' => $algorithme,
'form' => $form->createView(),
]);
}
}

I found the problem for those who will wondering is was
#auto_mapping:
# App\Entity\: []
that was uncomment in config/packages/validator.yaml
