The function Symfony\Component\Security\Core\Authentication\Token\TokenInterface::getRoles() has been deprecated: since Symfony 4.3, use the getRoleNames() method instead

            if ($role instanceof SwitchUserRole) {
                return $role->getSource()->getUser();
            }
        }

    }
