Node.js FB Messenger机器人程序：消息传递\u events.length-->；无法读取属性长度

您好，我的机器人有一个问题，即我的webhook没有及时响应facebook-我从开发者页面收到以下消息：

您对回调URL的Webhooks订阅至少有10分钟未接受更新。请验证您的回调服务器是否正常工作。请访问我们的参考文档，了解如何更新回调URL

如果您的回调URL在50分钟后仍然失败，您的订阅将被禁用。要重新激活，只需使用相同的参数发出POST请求，或访问应用程序仪表板中的Webhooks选项卡

因此，bot已被禁用。我的机器人托管在heroku上，当我转到webhook页面时，我得到以下结果：

[禁止]（）

然而，作为页面和bot应用程序的管理员，我仍然能够看到并测试bot的功能，即使是在开发者模式下。我已经验证了bot通过messenger返回正确的响应，但是webhook url仍然失败。有人能帮我吗？我的代码和日志将在下面找到
