I created this controller
<?php
namespace App\Controller;
use App\Interface\GetDataServiceInterface;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
#[Route('/api')]
class ApiController
{
    private GetDataServiceInterface $getDataService;
    public function __construct(GetDataServiceInterface $getDataService)
    {
        $this->getDataService = $getDataService;
    }
    #[Route('/products', name: 'products', methods: ['GET'])]
    public function products(): Response
    {
        
        return new Response(
            $this->getDataService->getData()
        );
    }
}
then I setted the autowiring for GetDataServiceInterface on services.yml
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.
    # 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/'
            - '../src/Entity/'
            - '../src/Kernel.php'
    
    App\Service\GetJsonDataService: ~
    App\Interface\GetDataServiceInterface: '@App\Services\GetJsonDataService'
this is the interface
<?php
namespace App\Interface;
interface GetDataServiceInterface
{
    public function getData():string;
}
and the service
<?php
namespace App\Service;
use App\Interface\GetDataServiceInterface;
class GetJsonDataService implements GetDataServiceInterface
{
    public function getData():string
    {
        return getcwd();
    }
}
but now I get this error when I try to make a request
The controller for URI "/api/products" is not callable: Controller "App\Controller\ApiController" cannot be fetched from the container because it is private. Did you forget to tag the service with "controller.service_arguments"?
I'm not sure what else I have to set
