I can fire events from Pusher debug console, but Laravel 5.2 isn't firing them - laravel-5

Question

I am able to fire dummy events from the Pusher debug console and my client side is able to pick them up. But when I try to fire the event from my UserController nothing seems to happen.
Here is my Event class
<?php
namespace App\Events;
use App\Events\Event;
use App\Player;
use App\Product;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class NewPurchase extends Event implements ShouldBroadcast
{
use SerializesModels;
public $product;
/**
* Create a new event instance.
*
* #param Product $product
* #return void
*/
public function __construct(Product $product)
{
$this->product = $product;
}
/**
* Get the channels the event should be broadcast on.
*
* #return array
*/
public function broadcastOn()
{
return [Player::where('user_id', $this->product->seller_id)->first()->group_id];
}
}
Here is my listener, which doesn't have anything because I want everything to be process client side
<?php
namespace App\Listeners;
use App\Events\NewPurchase;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
class NewPurchaseListener implements ShouldQueue
{
/**
* Create the event listener.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* #param NewPurchase $event
* #return void
*/
public function handle(NewPurchase $event)
{
//
}
}
Here is my .env
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=858577
PUSHER_APP_KEY=ec160cc0a1ca15e463f4
PUSHER_APP_SECRET=
QUEUE_DRIVER=sync
Here is my event service provider
class EventServiceProvider extends ServiceProvider
{
/**
* The event listener mappings for the application.
*
* #var array
*/
protected $listen = [
'App\Events\NewPurchase' => [
'App\Listeners\NewPurchaseListener',
],
];
And here is where the event is fired
Event::fire(new NewPurchase($product));

My issue was that my version of Laravel hadn't been updated from the previous developers. Therefore the version of Pusher I had wasn't compatible at first with the version of Laravel I was using. I have tweaked this now and it works.
