The service ".service_locator.VS38E50" has a dependency on a non-existent service "Gos\Bundle\WebSocketBundle\Pusher\Wamp\WampPusher".

MyController.php

<?php

use App\Repository\ProfileRepository;
use App\Repository\Repository;
use App\Websocket\WsNotificator;

class LanguageController extends BaseEntityController {

	/**
	 * @Route("/", name="default", methods={"GET"})
	 */
	public function defaultAction(Request $request): ?JsonResponse
	{

		/** @var PusherInterface $pusher */
		$pusher = $this->get('gos_web_socket.pusher.wamp');
		$pusher->push(['msg' => 'hello'], 'chat.topic');
		var_dump('ok');
		die;
	}

	public static function getSubscribedServices()
	{
		return array_merge(
			parent::getSubscribedServices(),
			[
				'gos_web_socket.pusher.wamp' => WampPusher::class,
			]
		);
	}

}

When I have method getSubscribedServices in my controller and clear cache I get following error:

The service ".service_locator.VS38E50" has a dependency on a non-existent service "Gos\Bundle\WebSocketBundle\Pusher\Wamp\WampPusher".

Missing something in my config?

Truthfully, I've never messed with the getSubscribedServices method, so I'm not entirely sure that the pushers will work with it (looking at what's in the abstract controller, all of those services are referenced by a class or interface name, and the pushers aren't registered in the container with those types of IDs).

You might be better off injecting the pusher as an argument to your controller instead of using the getSubscribedServices method. At least, https://symfony.com/doc/current/service_container/service_subscribers_locators.html doesn't give me much confidence that you can use it without having class-based service IDs.

thanks for answer, but when I try inject pusher as argument to my controller in costructor

/**
 * @Route("/api/language", name="language_api")
 */
class LanguageController extends BaseEntityController {

	private WsNotificator $wsNotificator;
	private PusherInterface $pusher;

	public function __construct(
		LoggerInterface $logger,
		LanguageRepository $repository,
		ProfileRepository $profileRepository,
		WsNotificator $wsNotificator,
		CacheInterface $cacheApp,
		PusherInterface $pusher
	){
		parent::__construct($logger, $repository, $profileRepository, $cacheApp);
		$this->wsNotificator = $wsNotificator;
		$this->pusher = $pusher;
	}

I get this error:

Cannot autowire service "App\Controller\LanguageController": argument "$pusher" of method "__construct()" references interface "Gos\Bundle\WebSocketBundle\Pusher\PusherInterface" but no such service exists. Did you create a class that implements this interface?

And When I try get service by name

	/**
	 * @Route("/", name="add", methods={"GET"})
	 */
	public function defaultAction(Request $request): ?JsonResponse
	{

		/** @var PusherInterface $pusher */
		$pusher = $this->get('gos_web_socket.pusher.wamp');
		$pusher->push(['msg' => 'hi'], 'chat.topic');
		die;
	}

I get error:

Service "gos_web_socket.pusher.wamp" not found: even though it exists in the app's container, the container inside "App\Controller\LanguageController" is a smaller service locator that only knows about the "doctrine", "form.factory", "http_kernel", "message_bus", "messenger.default_bus", "parameter_bag", "request_stack", "router", "security.authorization_checker", "security.csrf.token_manager", "security.token_storage", "serializer", "session" and "twig" services. Try using dependency injection instead.

but when I try bin/console debug:container gos_web_socket.pusher, service exist

Some idea? Thanks very much

You can't use autowiring to inject pushers, they all share a common interface (and are decorated in debug mode) so nothing can reliably set an alias to Gos\Bundle\WebSocketBundle\Pusher\PusherInterface in the service container. You're going to have to manually define that argument for your service configurations wherever you need it injected.

[ViktorieTrungerova]

I am sorry, I am newbie in symfony and I am not sure how do you think exactly.

I have registered only one pusher (wamp)

gos_web_socket:
   pushers:
      wamp: enabled: true
      host: 127.0.0.1
      port: 80
      ssl: false
      origin: null

You say that I have to manually define argument in my config like this?

App\Controller\LanguageController:
class: App\Controller\LanguageController:
arguments:
    $pusher: '@gos_web_socket.pusher.wamp'

My controller

class LanguageController extends BaseEntityController {

	private WsNotificator $wsNotificator;
	private WampPusher $pusher;

	public function __construct(
		WampPusher $pusher,
		LoggerInterface $logger,
		LanguageRepository $repository,
		ProfileRepository $profileRepository,
		WsNotificator $wsNotificator,
		CacheInterface $cacheApp
	){
		parent::__construct($logger, $repository, $profileRepository, $cacheApp);
		$this->wsNotificator = $wsNotificator;
		$this->pusher = $pusher;
	}

but I get error:

Cannot autowire service "App\Controller\LanguageController": argument "$pusher" of method "__construct()" references class "Gos\Bundle\WebSocketBundle\Pusher\Wamp\WampPusher" but no such service exists.

Same issue on prestashop v8.0.0 built on symfony

The service "PrestaShopBundle\Security\OAuth2\Repository\ClientRepository" has a dependency on a non-existent service "security.user.provider.concrete.oauth2".
