My Azure Bot Framework bot is not receiving any events from the connected Slack channel

Question

I have created an Azure Bot and it works in the web chat. I have connected a Slack channel to the bot and none of the Slack events being sent to the bot framework event endpoint are being converted into events and sent to my bot.

I have verified that the Slack bot is configured correctly by temporarily sending the Slack events to my own endpoint and there is high rate of traffic. Additionally, the bot metrics shows a significant number of requests being received. I have tested DMs to my bot as well as mentions in other channels where the bot has been added as a channel member.

Given that the Slack side seems to be set up correctly, what can I do to debug why none of those events are being converted to events and sent to my bot?

Answer 1

I have enabled the Analytics service and connected the logs up to my bot which was a little helpful. I'm able to see 404 errors that look correlated with every event coming from the Slack channel. It's not clear why the communication between the channel (managed by Microsoft) and the bot resource (managed by Microsoft) would have failed internal communications. The logs contain a painfully small amount of detail so it's not clear where to go from here.

I tried connecting it to a completely different Slack bot just to see if there was something wrong with the settings on the bot side and had the same results. I've triple checked that the Slack channel settings are correct.
