Service "fos_elastica.finder.app.user" not found - symfony

Question

Symfony can't find service for fos_elastica
Service "fos_elastica.finder.app.user" not found: even though it exists in the app's container, the container inside "App\Controller\DevController" is a smaller service locator that only knows about the "doctrine", "form.factory", "http_kernel", "parameter_bag", "request_stack", "router", "security.authorization_checker", "security.csrf.token_manager", "security.token_storage", "session" and "twig" services. Unless you need extra laziness, try using dependency injection instead. Otherwise, you need to declare it using "DevController::getSubscribedServices()".
my config
# Read the documentation: https://github.com/FriendsOfSymfony/FOSElasticaBundle/blob/master/Resources/doc/setup.md
fos_elastica:
clients:
default: { host: localhost, port: 9200 }
# indexes:
# app: ~
indexes:
app:

types:

properties:

persistence:
# the driver can be orm, mongodb, phpcr or propel
# listener and finder are not supported by
# propel and should be removed
driver: orm
model: App\Entity\User
provider: ~
listener: ~
finder: ~
my controller:
/**
* #Route("/search")
*/
public function searchElastic(){
/** var array of App\Entity\User */
$finder = $this->container->get('fos_elastica.finder.app.user');
return new response('N/A');
}
command php bin/console fos:elastica:populate didn't throw any errors and in phpstorm it isn't highlighted (it mean phpstorm found it)
Please help me.

Answer 1

You should use Dependency Injection like so:
Add use statement in the controller class use FOS\ElasticaBundle\Manager\RepositoryManagerInterface;, then your action should look like this:
/**
* #Route("/search")
*/
public function searchElastic(RepositoryManagerInterface $finder) {
$someResult = $finder->getRepository(User::class)->find(...);
return new response('N/A');
}
