Troubleshooting
If you get an error "no message for media type", then go into the Media type settings, and then its Message Templates tab and then add the Problem and Problem Recovery templates if they don't already exist, and then update.
If you get an error "not in channel" when sending the alert, you need to add your Slack APP to your Channel using the Slack UI.
