I using eloquent model in lumen scheduler but show error Call to a member function connection() on null but using DB work fine.

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Laravel\Lumen\Console\Kernel as ConsoleKernel;
use Models\Setting;

class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [];

    /**
     * Define the application's command schedule.
     *
     * @param \Illuminate\Console\Scheduling\Schedule $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $setting = Setting::find(1);
    }
}
