Symfony 3.4服务 - Doctrine \ ORM \ EntityManager的实例,给定布尔值

I currently have an error with a service since I updated to Symfony 3.4 from 3.0.

I have a SwitchUserListener which receives a couple of objects in its construct but it fails to receive the EntityManager even though i have it Type-Hinted. I also added a public key to my services

I get a FatalThrowableError because the class gets instantiated with a boolean instead of an EntityManager Object.

Error Message

Type error: Argument 10 passed to Dbm\UserBundle\Security\SwitchUserListener::__construct() must be an instance of Doctrine\ORM\EntityManager, boolean given, called in C:\wamp64\www\Portail\var\cache\dev\ContainerWyiblvw\getSecurity_Authentication_SwitchuserListener_MainService.php on line 8

FatalThrowableError Line

SwitchUserListener->__construct(object(TokenStorage), object(EmailUserProvider), object(UserChecker), 'main', object(TraceableAccessDecisionManager), object(Logger), '_switch_user', 'ROLE_ALLOWED_TO_SWITCH', object(TraceableEventDispatcher), false, object(AuthorizationChecker)) in var\cache\dev\ContainerWyiblvw\getSecurity_Authentication_SwitchuserListener_MainService.php

Here is what I have right now.

services.yml

services:
    _defaults:
        public: true
        autowire: true
        autoconfigure: true

    security.authentication.switchuser_listener:
        class: Dbm\UserBundle\Security\SwitchUserListener
        arguments:
            - '@security.token_storage'
            - ~
            - '@security.user_checker'
            - ~
            - '@security.access.decision_manager'
            - '@logger'
            - ''
            - ''
            - '@event_dispatcher'
            - '@doctrine.orm.entity_manager'
            - '@security.authorization_checker'
        tags:
            - { name: monolog.logger, channel: security }

SwitchUserListener.php

namespace Dbm\UserBundle\Security;
...
use Doctrine\ORM\EntityManager;

class SwitchUserListener implements ListenerInterface

    private $tokenStorage;

    private $providerKey;

    private $usernameParameter;
    private $role;
    private $logger;

                                $providerKey,

                                AuthorizationChecker $authCheck)
