Serialization of 'Symfony\Component\HttpFoundation\File\File' is not allowed
For Vich Uploader, you need to use implements Serialize use Serializable; Class EntityName implements Serialize { //code here public function serialize() { return serialize($this->getId()); } public function unserialize($serialized) { $this->id = unserialize($serialized); } } It works for me.
