Symfony 4 - KNP Menu - MenuBuilder не вызывается

Я перехожу с Symfony 3.3 на Symfony 4.

KNPMenu нормально работал под Symfony 3.3, но теперь я вижу это исключение:

An exception has been thrown during the rendering of a template ("The menu "main" is not defined.").

services.yaml

App\Menu\MenuBuilder:
    public: true
    tags:
        - { name: app.menu_builder.admin, method: createAdminMenu, alias: admin }
        - { name: app.menu_builder.calendar, method: createCalendarMenu, alias: calendar }
        - { name: app.menu_builder.main, method: createMainMenu, alias: main }
        - { name: app.menu_builder.trailer, method: createTrailerMenu, alias: trailer }
        - { name: app.menu_builder.user, method: createUserMenu, alias: user }

MenuBuilder

Namespace App\Menu;

use Knp\Menu\FactoryInterface;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;
use Symfony\Component\Security\Core\Security;

class MenuBuilder implements ContainerAwareInterface
{

    use ContainerAwareTrait;

    private $factory;

    /**
     * @param FactoryInterface $factory
     */
    public function __construct( FactoryInterface $factory )
    {
        $this->factory = $factory;
    }

Я помещаю die('here'); в __construct, он никогда не запускается.

Использование php bin / console debug: меню контейнера дает:

Как я могу запустить MenuBuilder __construct?
