Problem with autowiring RegistryInterface in ServiceEntityRepository - php

Question

I was following Symfony docs and wanted to use ServiceEntityRepository (link).
I created entity:
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\BetRepository")
*/
class Bet
{
....
Repository was automatically created:
namespace App\Repository;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Symfony\Bridge\Doctrine\RegistryInterface;
use App\Entity\Bet;
class BetRepository extends ServiceEntityRepository
{
public function __construct(RegistryInterface $registry)
{
parent::__construct($registry, Bet::class);
}
}
I wanted to create BetService which uses BetRepository:
namespace App\Service;
use App\Repository\BetRepository;
final class BetService
{
private $betRepository;
public function __construct(BetRepository $betRepository)
{
$this->betRepository = $betRepository;
}
finally I created a controller and wanted to inject BetService into it:
namespace App\Controller;
use App\Service\BetService;
final class BetController extends AbstractController
{
private $betService;
public function __construct(BetService $betService)
{
$this->betService = $betService;
}
}
Problem is I keep getting error:
Cannot autowire service "App\Repository\BetRepository": argument
"$registry" of method "__construct()" references interface
"Symfony\Bridge\Doctrine\RegistryInterface" but no such service
exists. Did you create a class that implements this interface?
my services.yaml is default one from installation:
parameters:
services:
# default configuration for services in *this* file
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
public: false
# makes classes in src/ available to be used as services
# this creates a service per class whose id is the fully-qualified class name
App\:
resource: '../src/*'
exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'
# controllers are imported separately to make sure services can be injected
# as action arguments even if you don't extend any base controller class
App\Controller\:
resource: '../src/Controller'
tags: ['controller.service_arguments']
I am using Symfony 4.2
I tried autowiring EntityManager to BetRepository however I get error that EntityManager constructor is not public and tbh I feel this is not the right approach as docs say it should work out of box.
I can provide composer.json (didn't initially as already question is quite long)
Thanks everyone in advance!
