Serialization of UploadedFile is not allowed - symfony

Question

I'm trying to upload a file via vichuploader bundle on my Users entity.
Using hwioauthbundle that implements UserInterface, and i think the errors comes from that bundle...
So every time i try to uplod a file i got this exception :
Serialization of 'Symfony\Component\HttpFoundation\File\UploadedFile'
is not allowed
I already tried this solution but also same exception.

My form Userstype:
use AppBundle\Form\FilesType;
->add('cv',FilesType::class)
My form Filestype:
-> add('imageFile',
VichFileType::class, [
'required' => false,
'allow_delete' => true,
'download_link' => true,
'label' => false,
]);

Answer 1

You are serializing ImageFile entity within this code that's why you are getting the error , try removing that and add updatedAt field so that doctrine can track changes on the entity:
/**
* Files
* #ORM\Table(name="files")
* #ORM\Entity(repositoryClass="AppBundle\Repository\FilesRepository")
* #Vich\Uploadable
*/
class Files implements \Serializable
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* NOTE: This is not a mapped field of entity metadata, just a simple property.
*
* #Vich\UploadableField(mapping="product_image", fileNameProperty="imageName", size="imageSize")
*
* #var File
*/
protected $imageFile;
/**
* #ORM\Column(type="string", length=255)
*
* #var string
*/
protected $imageName;
/**
* #ORM\Column(type="datetime")
*
* #var string
*/
protected $updatedAt;
public function getId()
{
return $this->id;
}
/**

public function setImageFile(File $image = null)

Answer 2

for Symfony5
Class User implement UserInterface
public function __serialize(): array
{
return [
'id' => $this->id,
'email' => $this->email,
//......
];
}
public function __unserialize(array $serialized): User
{
$this->id = $serialized['id'];
$this->email = $serialized['email'];
// .....
return $this;
}

Check this out, one of your Users's relation has an UploadedFile property, which is essentially a File aka a filestream which aren't allowed to be serialized. Therefore you need to specify what you want to serialized:
https://symfony.com/doc/3.3/security/entity_provider.html
Basically you only neeed to serialized id, username and password (three is an example code on the above page)
