Symfony 4 : problem with locale in Command - php

Question

I'm building a Symfony 4 application using locale.
My locale is binded in services.yaml :
parameters:
locale: 'en'
app_locales: en|fr|de|es|pt|
services:
_defaults:
autowire: true
autoconfigure: true
bind:
$locale: "#=service('request_stack').getCurrentRequest().getLocale()"
$listLocales: '%app_locales%'
App\:
resource: '../src/*'
exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'
App\Repository\:
esource: '../src/Repository'
Also, locale is injected and can be used in my repositories (used for elastic search request).
I need to add a command that uses one of my repositories to retrieve some data but I get this error:
In getSomeRepositoryService.php line 12:
Call to a member function getLocale() on null
var/cache/dev/ContainerJyByO4D/getSomeRepositoryService.php:
use Symfony\Component\DependencyInjection\Argument\RewindableGenerator;
use Symfony\Component\DependencyInjection\Exception\RuntimeException;
// This file has been auto-generated by the Symfony Dependency Injection Component for internal use.
// Returns the private 'App\Repository\SomeRepository' shared autowired service.
include_once $this->targetDirs[3].'/src/Repository/AbstractRepository.php';
include_once $this->targetDirs[3].'/src/Repository/SomeRepository.php';
return $this->privates['App\Repository\SomeRepository'] = new \App\Repository\SomeRepository(($this->privates['Elastica\Client'] ?? $this->load('getClientService.php')), ($this->services['request_stack'] ?? ($this->services['request_stack'] = new \Symfony\Component\HttpFoundation\RequestStack()))->getCurrentRequest()->getLocale());
Locale is injected in AbstractRepository constructor.
Here's my command (simplified version) :
classFooCommand extends Command
{
protected $someRepository;
public function __construct(SomeRepository $someRepository)
{
$this->someRepository = $someRepository;
parent::_construct();
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$demoData = $this->someRepository->getFoo();
var_dump($demoData);
}
}
How can the locale get injected in my command correctly?
