Zend Framework 2中控制台cron路由的参数无效

我正试图在zf2项目中制作一个cron应用程序，但它总是给我以下消息：

失败原因：无效参数或未提供参数

我的代码是：

module.config.php

'controllers' => array(
        'invokables' => array(
            'Sync'Controller'Cron' => 'Sync'Controller'CronController',
            'Sync'Controller'Index' => 'Sync'Controller'IndexController'
        ),
    ),
'console' => array(
        'router' => array(
            'routes' => array(
                'user-reset-password' => array(
                    'options' => array(
                        'route' => 'user resetpassword [--verbose|-v] <userEmail>',
                        'defaults' => array(
                            'controller' => 'Sync'Controller'Index',
                            'action' => 'password'
                        )
                    )
                ),
                'cron' => array(
                    'options' => array(
                        'route' => 'cron [full|center]',
                        'defaults' => array(
                            'controller' => 'Sync'Controller'Cron',
                            'action' => 'full'
                        )
                    )
                )
            )
        )
    )

CronController.php

class CronController extends AbstractActionController

｛

public function fullAction()
{
    $request = $this->getRequest();
    if (!$request instanceof ConsoleRequest) {
        throw new 'RuntimeException('You can only use this action from a console!');
    }
    return("hi");
}
public function centerAction()
{
}

}
