Php 取消序列化时Laravel通知失败

在我的forge生产服务器上，我已经配置了Laravel 5.3通知，所有通知都使用了

light\Bus\Queueable

特性，并实现了

light\Contracts\Queue\ShouldQueue

接口。这是在我创建的

App\Notifications\BaseNotification

类中完成的，我的所有通知类都进行了扩展

我还配置了一个工人来运行队列

一切都正常，但今晚我在执行通知时开始收到此错误：

Symfony\Component\Debug\Exception\FatalErrorException: Illuminate\Notifications\ChannelManager::sendNow(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "CenaZero\Notifications\Orders\OrderCompletedOwnerNotification" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition 
in /home/forge/cenazero.com.br/vendor/laravel/framework/src/Illuminate/Notifications/ChannelManager.php:64

报告错误的类的代码如下所示：

<?php

namespace CenaZero\Notifications\Orders;

use CenaZero\Models\Order;
use CenaZero\Notifications\BaseNotification;
use Illuminate\Notifications\Messages\MailMessage;
use NotificationChannels\Gcm\GcmMessage;
use NotificationChannels\Zenvia\ZenviaMessage;

class OrderCompletedProducerNotification extends BaseNotification
{
    private $order;

    public function __construct(Order $order)
    {
        $this->order = $order;
    }

    public function toMail($notifiable)
    {
        $data = [
            'order'    => $this->order,
            'item'     => $this->order->item,
            'product'  => $this->order->item->product,
            'producer' => $notifiable,
            'to'       => $notifiable->email,
        ];

        return (new MailMessage)
            ->view(['emails.orders.completed.producer', 'emails.orders.completed.producer-plain'], $data)
            ->subject($this->translation('subject'));
    }

    public function toZenvia($notifiable)
    {
        return ZenviaMessage::create()
                ->content($this->translation('message'))
                ->id('order-completed-producer-' . $this->order->id);
    }

    public function toGcm($notifiable)
    {
        return GcmMessage::create()
            ->title($this->translation('title'))
            ->message($this->translation('message'));
    }

    public function toArray($notifiable)
    {
        return [
            'id'          => $this->order->id,
            'status_id'   => $this->order->status_id,
            'message'     => $this->translation('title'),
            'description' => $this->translation('message'),
        ];
    }
}

此部分来自给定的错误消息

...Please ensure that the class definition 
"CenaZero\Notifications\Orders\OrderCompletedOwnerNotification" 
of the object you are trying to operate on was loaded...

显示该类不是自动加载的

将包含在
CenaZero
命名空间下使用的类的基本文件夹添加到的数组中。这样，在脚本尝试使用命名空间下的类反序列化对象之前，命名空间下的类将自动加载

composer.json

{
    "autoload": {
        "psr-4": {
            "CenaZero\\": "<relative-path-to-root-folder-of-namespace>/",
        }
    }
}

{
“自动加载”：{
“psr-4”：{
“CenaZero\\”：“/”，
}
}
}
