关于 Laravel Model Deleted 事件

具体就是我在 UserController 进行了 delete() 操作,
然后 UserObserver 又调用了 Job 队列, 会报 500 错误 findOrFail($id)

UserController 内容

class UserController extends Controller
{
     public function destroy($id)
    {
        $result = User::findOrFail($id);

        if ($result->delete()) {
             return 'Success';
         }
        return 'Failed';
    }
}

UserObserver 内容

class UserObserver
{
    public function deleted(User $user)
    {
          UserJob::dispatch($user);
    }
}

UserJob 内容

class UserJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function handle()
    {
        Log::info($this->user);
    }
}
