If the bot published is unattended for sometime (around 50 min), then an error comes stating "Unable to Connect". To mitigate this I tried using the "inactivity" trigger and set time duration, a message and an action to follow. But when I create a topic it is in "custom" and if I modify in "system" topic then also, that topic goes to "custom" and the trigger is not working when I test it. Can you suggest how to solve this error or provide any other solution?
