Symfony Bundle constructor arguments not passed (Autowire not working for custom bundle)

Question

I am developing a bundle JohnCorpFormsBundle for my own symfony projects to share extended form logic.

However, when implementing the bundle in a project myproject I always get an error when I load a page in myproject that relies on bundle logic.

Error Message:

Too few arguments to function
JohnCorp\FormsBundle\Form\Builder\Core\ListFilterType::__construct(),
0 passed in /var/www/myproject/vendor/symfony/form/FormRegistry.php on line 81 and exactly 1 expected

It seems, the parameter $requestStack is not being passsed to ListFilterType::__construct() but shouldn't this work automatically using autowire?

MyProject: Controller-Code that causes the error:

// UserListController.php

use JohnCorps\FormsBundle\Form\Builder\Core\ListFilterType;
// ...

// this line runs into the error:
$listFilterForm = $this->createForm(ListFilterType::class);

Bundle: Form class:

// ListFilterType::class

namespace JohnCorp\FormsBundle\Form\Builder\Core;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\HttpFoundation\RequestStack;

class ListFilterType extends AbstractType
{

    protected RequestStack $requestStack;

    public function __construct(RequestStack $requestStack)
    {
        $this->requestStack = $requestStack;
    }

    //...

Bundle: Extension

// src/DependencyInjection/JohnCorpFormsExtension.php

namespace JohnCorp\FormsBundle\DependencyInjection;

class JohnCorpFormsExtension extends Extension
{
    /**
     * {@inheritdoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.yaml');
    }
}

Bundle: composer.json autoload

{
  "name": "johncorp/forms-bundle",
  "type": "symfony-bundle",
  
  ...

  "autoload": {
    "psr-4": {
      "JohnCorp\\FormsBundle\\": "src/"
    }
  }
}

I tried adding the arguments explicitly in the bundles services.yaml to ensure autowire is not a problem, but that does not change a thing.

Bundle: src/Resources/config/services.yaml:

services:
    JohnCorp\FormsBundle\Form\Builder\Core\ListFilterType:
        arguments:
            $requestStack: '@request_stack'

I am not sure if this is required or if it is loaded. (I include this in a src/DependencyInjection/JohnCorpFormsExtension.php)

I also tried adding the yaml-Code from above directly inside the projects services.yaml without any effect.

I also tried explicitly using autowire-Attribute in ListFilterType.php

// ListFilterType::class

public function __construct(
    #[Autowire(service: 'request_stack')] RequestStack $requestStack
)

If you use Symfony 6 , you just have to set the autowire and autoconfigure as true in your Bundle like this :

# yourBundle/src/Ressources/config/services.yaml
services:
    JohnCorp\FormsBundle\Form\Builder\Core\ListFilterType:
        autowire: true
        autoconfigure: true

here is the doc : service-container-services-load-example

then after that you have to inject your service in your BundleExtension:

<?php
//yourBundle/src/DepencencyInjection/YourBundleExtension
namespace App\YourBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;
use Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;

class YourBundleExtension extends Extension implements PrependExtensionInterface
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.yaml');
    }
...
}
