Laravel 授权停止工作 VKontakte

一个月后，VKontakte 对 Laravel 项目的授权停止工作。使用了社交名流包。现在，当我登录时，我收到此错误：

VkontakteProvider.php 第 92 行中的 InvalidStateException：

我查看了VK返回的内容，原来是302错误。

由于令牌的生命周期已经结束，我理解该错误。

它在这里抛出一个错误：

if ($this->hasInvalidState()) {
    throw new InvalidStateException();
}

但是我的知识不足以理解为什么，你能解释一下吗？

这是错误页面：

这是文件VkontakteProvider.php：
