Warning: Header may not contain more than a single header,

Bonjour à la communauté.

Je suis nouveau sous symfony 5
Je travaille avec la version suivante : Symfony CLI version 5.10.6 (c) 2021-2025 Fabien Potencier (2025-01-02T13:30:55Z - stable)

Mon probleme a débuté des que j'"ai installé la securité sur un site local de commerce. En effet avant je pouvais naviguer de la liste des produits au formulaire de mise a jour ,mais maintenant symfony m'affiche une erreur de header sans que je ne vois où ça correspond dans mon code.(Erreur:"Warning: Header may not contain more than a single header, new line detected")

Je ne vois pas où est parametré le header de la response dans mon controlleur

J'ai fais bcp de recherches sur les forums mais je ne trouve pas la solution

voici le code du controleur
