使用调度程序

我正在Windows中创建一个任务调度程序，只要保证在两个月后到期，就会发送一封电子邮件。运行Trying to get property of non-object之后我收到异常php artisan schedule:run这是我创建的命令SendEndRenewal.php 

<?php

namespace App\Console\Commands;

use App\Device;
use App\Mail\EndRenewal;
use Carbon\Carbon;
use Illuminate\Support\Facades\Mail;
use Illuminate\Console\Command;

class SendEndRenewal extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'send:renewals';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Email ending renewals';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $str = "";
        $devices = Device::whereYear('endDate','=',Carbon::now()->year)->whereMonth('endDate','=',Carbon::now()->month+2)->get();
        if (!empty($devices)) {
            foreach ($devices as $device) {
                Mail::to('vjztingson@gmail.com')->send(new EndRenewal($device));
                $str .= "sent " . $device->name . " ";
            }
        }
        $this->info($str);
    }
}

这是我的电子邮件对象EndRenewal.php 

<?php

namespace App\Mail;

use App\Device;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class EndRenewal extends Mailable
{
    use Queueable, SerializesModels;

    public $device;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct(Device $device)
    {
        $this->device = $device;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->view('devices.show', ['device'=>$this->device]);
    }
}

当我在build()中的EndRenewal.php中返回测试空白页时，它会起作用，但是当我传递一个对象并返回该对象的视图时它不起作用。我尝试了protected $device而不是公开它仍然没有用。请帮忙。谢谢！

我尝试了print_r它返回的传递对象
