Nette 2.3.0 beta: Nette\Caching\Storages\FileStorage

Upgradoval jsem na Nette 2.3.0 beta. A tracy mi hlásí tuto chybu:

Nette\DI\ServiceCreationException

Service ‚55_App_Router_CachedDatabaseRouterHelper‘: Service of type Nette\Caching\Storages\FileStorage needed by App\Router\CachedDatabaseRouterHelper::__construct() not found. Did you register it in configuration file?

config.neon:

services:
    - App\Factory\ContainerLocatorFactory
    - App\RouterFactory
    - App\Router\CachedDatabaseRouterHelper
    - App\Factory\SearchFactory

CachedDatabaseRouterHelper.php:

<?php

namespace App\Router;

use App;
use Nette;

class CachedDatabaseRouterHelper extends Nette\Object
{
    /** @var App\Model\User*/
    protected $userRepository;

    protected $cache;

    public function __construct( App\Model\User $userRepository, Nette\Caching\Storages\FileStorage $storage )
    {
        $this->userRepository= $userRepository;
        $this->cache = new Nette\Caching\Cache( $storage, 'CachedDatabaseRouterHelper' ); // Klidně té Cache dej lepší namespace… ;)
    }

	//moje funkce...
}

Co je špatně?
