Symfony 3.1 и OneUpUploaderBundle + FineUploader = UploadListener не вызывается

ВСТУПЛЕНИЕ

Я развиваюсь на Windows 10 Pro с XAMPP [1] который включает PHP v7.0.8,

• [1] XAMPP для Windows

Я использую Symfony v3.1.2, OneupUploaderBundle а также FineUploader для того, чтобы загрузить файлы на сервер.

При настройке я следовал документации OneUpUploaderBundle [2] и FineUploader [3], [4].

• [2] OneupUploaderBundle документация
• [3] Пример OneupUploaderBundle FineUploader
• [4] FineUploader загрузить документацию

ПРОБЛЕМА

Загрузка файлов работает нормально, и файлы загружаются в oneup_uploader_endpoint('gallery'),

Однако слушатель не вызывается и отображается в разделе «События Symfony Profiler». Not Called Listeners

КОД

соответствующая часть services.yml

app.upload_listener:
class: AppBundle\EventListener\UploadListener
tags:
- { name: kernel.event_listener, event: oneup_uploader.post_persist.default_uploader, method: onUpload }

мой слушатель загрузки

<?php

namespace AppBundle\EventListener;

use Oneup\UploaderBundle\Event\PostPersistEvent;

class UploadListener
{
public function onUpload(PostPersistEvent $event)
{
$request = $event->getRequest();
$original_filename = $request->files->get('fineuploader')->getClientOriginalName();
echo $original_filename;
}
}
