Symfony 4 - KNP菜单 - 未调用MenuBuilder

I am upgrading from Symfony 3.3 to Symfony 4.

KNPMenu was running fine under Symfony 3.3, but now I am seeing this exception:

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;
    }

I put a die('here'); in the __construct, it is never executed.

Using php bin/console debug:container menu yields:

    This answer was helpful: How to avoid "knp_menu.factory" deprecation?

    services.yaml

    app.menu_builder:
        class: App\Menu\MenuBuilder
    
    app.menu.main:
        class: Knp\Menu\MenuItem
        factory: ['@app.menu_builder', 'createMainMenu']
        arguments: { $options: [] }
        tags:
        - { name: knp_menu.menu, alias: main }
    

    I used php bin/console debug:autowiring security to get the security authorization checker

    Then I updated MenuBuilder.php like so:

    Namespace App\Menu;
    
    use Knp\Menu\FactoryInterface;
    use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;
    
    class MenuBuilder
    {
    
        private $factory;
        private $security;
    
        /**
         * @param FactoryInterface $factory
         */
        public function __construct( FactoryInterface $factory, AuthorizationCheckerInterface $security )
        {
            $this->factory = $factory;
            $this->security = $security;
        }
    

    Adding the SecurityAuthorizationChecker allows me to control the menu items offered with this statement:

    if( $this->security->isGranted( 'IS_AUTHENTICATED_FULLY' ) )
