Laravel命令队列异常

Question

我试图实现一个Laravel 5队列，它发送一个新的事件邮件到邮件列表。我发现你可以使用Command来做这件事，但每次我尝试执行这个命令时，我都会得到一个错误异常（见下文）。我已经写做邮件类是以下

<?php namespace App\Commands; 

use Illuminate\Support\Facades\App; 
use \App\Event; 
use Illuminate\Support\Facades\Mail; 
use Illuminate\Queue\SerializesModels; 
use Illuminate\Queue\InteractsWithQueue; 
use Illuminate\Contracts\Bus\SelfHandling; 
use Illuminate\Contracts\Queue\ShouldBeQueued; 

class EventMailing extends Command implements SelfHandling, ShouldBeQueued { 

    use InteractsWithQueue, SerializesModels; 

    /** 
    * Create a new command instance. 
    * 
    * @return void 
    */ 

    public $event; 
    public $recipients; 

    public function __construct(Event $event, $recipients) 
    { 
     $this->event=$event; 
     $this->recipients=$recipients; 
    } 

    /** 
    * Execute the command. 
    * 
    * @return void 
    */ 
    public function handle(EventMailing $command, User $user) 
    { 
     $event = $command->event; 

     print_r($event); 

     /* foreach ($this->recipients as $recipient) { 
      Mail::send('emails.event', $event, 
       function($message) use ($event,$recipient) 
       { 
        $message->from('info@gsebelux.org', 'GSE BeLux'); 
        $message->subject('New event: '.$event->name); 
        $message->to($recipient); 
       } 
      ); 
     }*/ 
    } 

} 

注：我注释掉的邮件部分来检查，如果不是那部分是不正常。

从控制器我称之为EventMailing命令是这样的：

public function sendMail($event,$array) 
{ 
    Queue::push(new EventMailing($event,$array)); 
} 

当我触发这个功能，我做了PHP的工匠队列：工作--verbose 我得到这个。任何人都可以帮我解决这个问题吗？

变化

public function handle(EventMailing $command, User $user) 
{ 
    $event = $command->event; 

    print_r($event); 

通过

public function handle(User $user) 
{ 
    //event is in the constructor 
    $event = $this->event; 

    print_r($event);
