Uploader un avatar pour les User

Bonjour à tous,

Je galère depuis plusieurs jours sur une fonctionnalité que je cherche à implémenter sur l'espace utilisateur l'ajout d'un avatar depuis une image.

Soit j'ai ce message

Citation:

Serialization of 'Symfony\Component\HttpFoundation\File\UploadedFile' is not allowed

soit l'upload / l'update ne fonctionne pas.

Déjà que je n'ai plus trop de cheveux sur la tête mais je continue à me les arracher.

Pour palier au message d'erreur j'ai implémenté l'interface \Serialize avec les functions requises mais là pas d'upload et quand j'y arrive en bidouillant pas d'update :(

Je vous partage mon code dites moi ce que vous en pensez :

User Entity
