Laravel эхо-уведомления + сокет io, не получая уведомления

Question

Итак, у меня есть laravel echo setup, класс уведомлений, и я слушаю канал App.User. {Id} на стороне клиента, однако всякий раз, когда я слушаю уведомления, я ничего не получаю. Мой laravel эхо-сервер работает;

[18:11:06] - Preparing authentication request to: http://localhost:3000
[18:11:06] - Sending auth request to: http://localhost:3000/broadcasting/auth

[18:11:07] - HTQYvo_jRsIn9YNbAAAE authenticated for: private-App.User.1
[18:11:07] - HTQYvo_jRsIn9YNbAAAE joined channel: private-App.User.1

Мой NotifyUser.class

class NotifyUser extends Notification implements ShouldQueue, ShouldBroadcast
{

    public function via($notifiable)
    {
        return ['database', 'broadcast'];
    }

    public function toBroadcast($notifiable)
    {
        return new BroadcastMessage([
            'notification' => 1,
            'message' => $this->message,
            'orderId' => $this->orderId
        ]);
    }
}

Мой интерфейс:

import Echo from "laravel-echo";

window.io = require('socket.io-client');

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001'
});

Прослушивание уведомлений:

 Echo.private(`App.User.${this.user.id}`)
                .notification((notification) => {
                    console.log(notification);
                });

Мой слушатель очереди:
