Hi @LaurentStar . The error means that the connection between your Rasa assistant and the Slack webserver hasn’t been established. A few things I’d check:
When you provided your webhook url did it get verified?
When you provided your webhook url was your Rasa server running (did you have your assistant running on your local machine)?
How do I change incoming http are request are validate? How do I see the post request sent by slack? Whatever slack is sending my webapp/chatbot is not accepting. This is why I get the message above. I seen this issue pop up 4 times and each time it is unresolved.
Hi @LaurentStar. I just followed the instructions we have on the docs and things seem to be working fine. I think this has to do with the webhook url you are providing. Are you sure you start the ngrok on the same port as your Rasa assistant? By default the port should be 5005, so you should start your ngrok as follows:
ngrok http 5005
Once it’s up and running, copy the given url, for example: https://5d3e6d8d0b32.ngrok.io and add the suffix of webhooks/slack/webhook at the end. The URL you should be providing to your Slack app configuration should look as follows:
This rasa doc webpage seems to address my issue but I have no idea what files the code should go into or when anything will be called. I am not able to comprehend this page or its associated github
I’m having this same issue. I’ve tripled checked all my info, have rasa server running and ngrok activated. I’m following the Slack Integration Documentation. But I keep getting this error:
Hello @mpickard I got the same issue mate. Rasa server and action server are running and still I’m getting this same challenge parameter issue. How did you solve it if you did?
