Salut,

Dans ton filtre tu as

        ->add('image', TextType::class, [
            'required' => true
        ])

mais dans ton form il n'est pas présent est donc jamais affiché je pense

        $builder
            ->add('brand')
            ->add('year')
            ->add('price')
            ->add('imageFile',VichImageType::class)
            ->add('isNew')

Pourtant dans ton entité ce champ ne peut pas être null.

Internal Server Error Expected argument of type "string", "null" given at property path "image".
