Muliti Module Project Error

Hi guys, I'm having some issue on multimodule project on my screen it display an error

Fatal error: Declaration of ModuleFrontPage\Module::registerAutoloaders() must be compatible with Phalcon\Mvc\ModuleDefinitionInterface::registerAutoloaders(Phalcon\DiInterface $dependencyInjector = NULL) in /path/to/my/project/app/app-frontpage/Module.php on line 12

here is my Module.php in app/app-frontpage/Module.php

<?php

namespace ModuleFrontPage;

use \Phalcon\Loader;
use \Phalcon\Mvc\View;
use \Phalcon\DiInterface;
use \Phalcon\Mvc\Dispatcher;
use \Phalcon\Mvc\ModuleDefinitionInterface;

class Module implements ModuleDefinitionInterface
{
    /**
     * Register a specific autoloader for the module
     */
    public function registerAutoloaders(DiInterface $di)
    {
        $loader = new Loader();

        $loader->registerNamespaces(
            array(
                'ModuleFrontPage\Controllers' => '../app/app-frontpage/controllers/',
                'ModuleFrontPage\Models'      => '../app/app-frontpage/models/',
            )
        );

        $loader->register();
    }

    /**
     * Register specific services for the module
     */
    public function registerServices(DiInterface $di)
    {
        // Registering a dispatcher
        $di->set('dispatcher', function () {
            $dispatcher = new Dispatcher();
            $dispatcher->setDefaultNamespace("ModuleFrontPage\Controllers");
            return $dispatcher;
        });

        // Registering the view component
        $di->set('view', function () {
            $view = new View();
            $view->setViewsDir('../app/app-frontpage/views/');
            return $view;
        });
    }
}

and my index.php

<?php

error_reporting(E_ALL);
define('APP_PATH', realpath('..'));

use \Phalcon\Mvc\Router;
use \Phalcon\Mvc\Application;
use \Phalcon\DI\FactoryDefault;
use \Phalcon\Debug;

//(new Debug())->listen();

$di = new FactoryDefault();

try {

    $config = require(APP_PATH.'/app/config/config.php');
    require(APP_PATH.'/app/config/loader.php');
    require(APP_PATH.'/app/config/services.php');
    require(APP_PATH.'/app/config/router.php');

    // Create an application
    $application = new Application($di);

    // Register the installed modules
    $application->registerModules(
        array(
                'AppFrontPage' => array(
                    'className' => 'ModuleFrontPage\Module',
                    'path'      => APP_PATH.'/app/app-frontpage/Module.php'
                )
            )
    );

    // Handle the request
    echo $application->handle()->getContent();

} catch (\Exception $e) {
    echo $e->getMessage();
}

router.php

<?php

//Registering a router
$di->set('router', function(){

    $router = new \Phalcon\Mvc\Router();

    $router->setDefaultModule("AppFrontPage'");

    $router->add('/', array(
        'module' => 'AppFrontPage',
        'controller' => 'index',
        'action' => 'index',
    ));

    return $router;
});
