symfony php8 dependency-injection PHP

I'm having a hard time understanding Does anyone know how to I'm experiencing a frustrating scenario with dependency injection in my Symfony 5.4 application using PHP 8.1. Despite properly configuring my service definitions, my service is not receiving the expected dependencies. I've defined a service in `services.yaml` as follows: ```yaml services: App\Service\MyService: arguments: $dependency: '@App\Service\MyDependency' ``` My `MyService` class looks like this: ```php namespace App\Service; class MyService { private $dependency; public function __construct(MyDependency $dependency) { $this->dependency = $dependency; } } ``` However, when I try to use `MyService`, I get the following behavior: ``` Argument 1 passed to App\Service\MyService::__construct() must be an instance of App\Service\MyDependency, none given. ``` I've verified that `MyDependency` is indeed defined as a service. Here's how it's set up: ```yaml services: App\Service\MyDependency: # some configurations here ``` I've cleared the cache multiple times using `php bin/console cache:clear`, and I've double-checked that the namespaces are correct. I also tried using autowiring by removing the explicit service definition in `services.yaml`, but the behavior continues. Is there something I'm missing in the configuration? Any insights or suggestions on how to debug this scenario would be appreciated. I'm developing on Ubuntu 20.04 with Php. I'd really appreciate any guidance on this. I recently upgraded to Php stable. Am I approaching this the right way?
