POST 405方法未找到 - Slack在集成聊天机器人时出现的错误

Question

当我把我的rasa聊天机器人和slack整合在一起的时候，我得到了某种405方法未找到的错误。请给我一些提示。

这是我在运行ngrok与slack整合时得到的错误。 Slack错误:

HTTP Requests ------------- POST /webhooks/slack/webhook 201 Created POST /webhooks/slack/webhook 200 OK POST /webhooks/slack/webhook 200 OK POST / 405 Method Not Allowed

我也面临同样的问题。它说''(home)上不允许发布。不知道为什么slack要在''(home)上发布事件请求，它应该在'webhooksslackwebhook'上发布，所以当我用postman发布webhook URL和示例信息时(https:/api.slack.comeventsmessage)很顺利。

问题为你解决了。

谢谢你，Vivek
