botman: no answer, no exception

I just made like in tutorial

use Mpociot\BotMan\BotManFactory;
use Mpociot\BotMan\BotMan;
use Mpociot\BotMan\Storages\Drivers\FileStorage;

$token = 'MY-TOKEN';
$config =  [
    'facebook_token' => $token,
    'facebook_app_secret' => 'MY-SECRET',

];

// $storage = new FileStorage(__DIR__);
// create an instance
$botman = BotManFactory::create($config);
$botman->verifyServices($token);

$botman->hears('foo', function ($bot) {
    $bot->typesAndWaits(2);
    $bot->reply('Hello World');
});
// give the bot something to listen for.
$botman->hears('.*', function (BotMan $bot) {
    $bot->reply('Hello yourself.');
});

// start listening
$botman->listen();

I see in logs…that facebook made request to my address. but no answer appear. Also didn’t get anythng in error log.
