So I have an issue to make the communication possible between Slack and BotFramework. I deploied once a bot on Slack to test the deployment and everything was working fine. I worked on another bot and when I try to deploy it there is no message reaching the bot on Azure.
Since I can not see errors on Azure or from Slack, I think my issue does not come from my code. What seems very strange is that I did not get any message from Slack telling me that the messages can not reach the bot and yet I can not see message reaching Azure.
I use this to install the bot on Slack https://docs.microsoft.com/en-us/azure/bot-service/bot-service-channel-connect-slack except that I did not suscribe to events which was working fine with my initial deployment.
I tried with a sample bot, I got the same issue. So I must be missing something about the configuration.
My bot is working fine with cortana and directline.
