The method getID() does not exist on Symfony\Component\Security\Core\User\UserInterface. It seems like you code against a sub-type of Symfony\Component\Security\Core\User\UserInterface such as App\Entity\UserSystem\User.

            return 'user$_' . User::ID_ANONYMOUS;
        }

        //In the most cases we can just use the username (its unique)
        return "user_" . $user->getUsername();
    }
