为什么我的事件侦听器没有被触发？

问：

我想在创建收据后向用户发送电子邮件。我有一个收据控制器，它创建一个控制器，然后触发一个事件，收据创建事件，它应该触发一个侦听器，发送收据通知，它应该发送邮件（我先用一个工作尝试过）。 法典： 收据创建事件：

<?php
 
namespace App\Events;
 
use App\Models\Racun;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
 
class ReceiptCreatedEvent
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
 
    /**
     * Create a new event instance.
     */
 
    public function __construct(public Racun $receipt)
    {
 
        $this->receipt = $receipt;
    }
 
    /**
     * Get the channels the event should broadcast on.
     *
     * @return array<int, \Illuminate\Broadcasting\Channel>
     */
    public function broadcastOn(): array
    {
        return [
            new PrivateChannel('channel-name'),
        ];
    }
}

听者：

<?php
 
namespace App\Listeners;
 
use App\Events\ReceiptCreatedEvent;
use App\Mail\ReceiptCreatedNotification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Support\Facades\Mail;
 
class SendReceiptNotification
{
    /**
     * Create the event listener.
     */
    public function __construct()
    {
        //
    }
 
    /**
     * Handle the event.
     */
    public function handle(ReceiptCreatedEvent $event): void
    {   info("This is the receipt: " . $event->receipt);
        Mail::to($event->receipt->user->email)->send(new ReceiptCreatedNotification($event->receipt, $event->receipt->user));
        //SendMailJob::dispatch($event->receipt);
    }
}

收据控制器：

<?php
 
namespace App\Http\Controllers;
 
use App\Events\ReceiptCreatedEvent;
use App\Mail\ReceiptCreatedNotification;
use App\Models\Artikal;
use App\Models\Racun;
use Illuminate\Foundation\Auth\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Response;
 
class RacunController extends Controller
{
    //
    public function ajaxStore(Request $request){
        $this->authorize('storeReceipt', auth()->user());
        $data = $request->all();
 
        $racun = Racun::create(
            [
                'user_id' => $data['user_id'],
                'hladnjaca_id' => $data['hladnjaca_id'],
                'artikal_id' => $data['artikal'],
                'datum' => now()->format('Y-m-d H:i:s'),
                'ulaz_gajbi' => $data['ulaz'],
                'izlaz_gajbi' => $data['izlaz'],
                'bruto' => $data['bruto'],
                'neto' => $data['neto'],
                'cena_po_kg_pdv' => Artikal::find($data['artikal'])->cena_sa_pdvom,
                'cena_po_kg_bez_pdv' => Artikal::find($data['artikal'])->cena_bez_pdva,
                'ukupno_cena_pdv' => $data['iznos_sa_pdvom'],
                'ukupno_cena_bez_pdv'=> $data['iznos_bez_pdva']
            ]
        );
       //Mail::to($racun->user->email)->send(new ReceiptCreatedNotification($racun, $racun->user));
 
        $response = [
            'message' => 'success'
        ];
       ReceiptCreatedEvent::dispatch($racun);
       return Response::json($response);
    }
}

活动和听众的注册：

protected $listen = [
    Registered::class => [
 
       SendEmailVerificationNotification::class,
    ],
    ReceiptCreatedEvent::class => [
        SendReceiptNotification::class,
    ],
];

邮件有效，我已经在没有侦听器的情况下尝试过，所以这不是问题。侦听器没有触发，所以日志中没有任何内容，我尝试过 info（） 助手，但什么都没有......
