"Missing Service" When declare new Topic in Symfony

Question

I'm implementing sockets on my app, so I did these steps:

1. Create the topic handler service, like this but with an Entity Manager on his __construct method.

   public function __construct(EntityManager $em, ClientManipulatorInterface $client) {
       $this->em = $em;
       $this->client = $client;
   }
   

2. Register your service with symfony.

   2.1. The file services.yml looks like this:

   foo.topic: 
       class: AppBundle\Topic\FooTopic
       arguments:["@doctrine.orm.personem_entity_manager", "@gos_web_socket.websocket.client_manipulator"]
       tags:
         -{ name: gos_web_socket.topic}
   

   And here is when i get the error Missing service in the first argument passed. I can not found my Entity Manager but i have declared it in my conf file.

   personem:
       dql:
         string_functions:
           convert: AppBundle\Dql\ConvertFunction
       connection: connection
       mappings:
         GptIReunionBundle: ~
         AppBundle: ~
   

Any ideas?

Answer 1

The problem was, that im using service.yml when im in local enviroment and im not declared Entity Manager in my config_prod.yml file.

So i solved creating the entity manager in all enviroments.
