Problem with translations and api platform symfony - symfony

Question

I have a problem with translation in symfony.
I have installed "symfony/translation": "4.4.*"
My translation configuration is
framework:
default_locale: "%locale%"
translator:
default_path: '%kernel.project_dir%/translations'
fallbacks:
- '%locale%'
I have an EventSubscriber called LocaleSubscriber
class LocaleSubscriber implements EventSubscriberInterface
{
private $availableLocales;
private $defaultLocale;
private $translatableListener;
protected $currentLocale;
public function __construct(
TranslatableListener $translatableListener,
LocaleRepository $localeRepository)
{
$this->translatableListener = $translatableListener;
$this->availableLocales = $localeRepository->getAvailableLocales();
$this->defaultLocale = $localeRepository->getDefaultLocale();
}
public static function getSubscribedEvents()
{
return array(
KernelEvents::REQUEST => ['onKernelRequest', EventPriorities::PRE_WRITE],
KernelEvents::RESPONSE => ['setContentLanguage']
);
}
public function onKernelRequest(RequestEvent $event)
{
// Persist DefaultLocale in translation table
$this->translatableListener->setPersistDefaultLocaleTranslation(true);
/** #var Request $request */
$request = $event->getRequest();
if ($request->headers->has("X-LOCALE")) {
$locale = $request->headers->get('X-LOCALE');
if (in_array($locale, $this->availableLocales)) {
$request->setLocale($locale);
} else {
$request->setLocale($this->defaultLocale);
}
} else {
$request->setLocale($this->defaultLocale);
}
// Set currentLocale
$this->translatableListener->setTranslatableLocale($request->getLocale());
$this->currentLocale = $request->getLocale();
}
/**
* #param ResponseEvent $event
* #return \Symfony\Component\HttpFoundation\Response
*/
public function setContentLanguage(ResponseEvent $event)
{
$response = $event->getResponse();
$response->headers->add(array('Content-Language' => $this->currentLocale));
return $response;
}
}
Its set the language for all request with X-LOCALE header (I send it from angular app)
So I have a Controller for RecoverPassword
class RecoverPasswordAction
{
/**
* #var ValidatorInterface
*/
private $validator;
/**
* #var EntityManagerInterface
*/
private $entityManager;
/**
* #var JWTEncoderInterface
*/
private $encoder;
/**
* #var UserLoadService
*/
private $userLoadService;
/**
* #var TranslatorInterface
*/
private $translator;
public function __construct(
ValidatorInterface $validator,
EntityManagerInterface $entityManager,
JWTEncoderInterface $encoder,
UserLoadService $userLoadService,
TranslatorInterface $translator
)
{
$this->validator = $validator;
$this->entityManager = $entityManager;
$this->encoder = $encoder;
$this->userLoadService = $userLoadService;
$this->translator = $translator;
}
public function __invoke(UserRecoverPassword $data, RequestStack $requestStack)
{
**var_dump($this->translator->trans('symfony.great'));die;**
$token = $requestStack->getMasterRequest()->attributes->get('token');
$this->validator->validate($data);
try{
$vars = $this->encoder->decode($token);
$user = $this->userLoadService->getUser($vars['email']);
$this->userLoadService->recoverPasswordUser($user, $data->newPassword);
}catch (\Exception $exception){
return new JsonResponse(['status' => 'FAILED', 'message' => $this->translator->trans($exception->getMessage())],500);
}
//return new JsonResponse(['status' => 'OK', 'message' => 'The password of '.$user->getUsername().' was recover']);
return new JsonResponse([
'status' => 'OK',
'message' => $this->translator->trans(
'user.success',
[],
'messages',
$requestStack->getCurrentRequest()->getLocale()
)
]);
}
}
But when I request this endpoint, I get this response
string(13) "symfony.great"
However the validation errors runs ok, I don't know why. what am i missing?
