Laravel Notification "Cannot unpack array with string keys" when implements ShouldQueue - laravel

Question

I want to send Notification using Queues in Laravel Framework 6.18.20.
$user->notify( new UserRegistrationSMSSend(
$user->phone,
$user->getMeta('phone_verification_code')
));
I created notification named "UserRegistrationSMSSend".
<?php
namespace App\Notifications;
use App\Channels\SMSChannel;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
class UserRegistrationSMSSend extends Notification implements ShouldQueue
{
use Queueable;
private $phone;
private $code;
/**
* Create a new notification instance.
*
* #return void
*/
public function __construct($phone, $code)
{
$this->phone = $phone;
$this->code = $code;
}
/**
* Get the notification's delivery channels.
*
* #param mixed $notifiable
* #return array
*/
public function via($notifiable)
{
return [SMSChannel::class];
}
/**
* Get the sms representation of the notification.
*
* #param mixed $notifiable
* #return \Illuminate\Notifications\Messages\MailMessage
*/
public function toSMS($notifiable)
{
if (\App::environment('production')) {
\LaravelLsimSms::sendSms(
$this->phone,
__('Code is :code', ['code'=>$this->code])
);
}
}
/**
* Get the array representation of the notification.
*
* #param mixed $notifiable
* #return array
*/
public function toArray($notifiable)
{
return [
//
];
}
}
When I'm calling this function result is "Cannot unpack array with string keys"
When I'm commenting out implements ShouldQueue it's working. What is the problem actually? Need your help.

This is the full log of returned error. And CACHE_DRIVER in .env file is array
