Catch all intent

I finally have Rhasspy and HA working (sort of, can’t get TTS to work on Rhasspy). I have a few intents in my configuration and they work but the problem is when Rhasspy sends an intent that is not not HA configuration, an error is thrown in HA log. Is there a way to have a catch all intent that would reply with something like “I am sorry, I don’t know how to do that” ?
