I still cringe thinking about it.

Meh, as a sibling comment points out, it's a demo, it'll happen. And when it happens, it's a teachable moment (assuming you can keep your head together as your demo falls apart before your very eyes): "Ah, so as you can see it's import to set the $DO_NOT_DISPLAY_PLAIN_TEXT_CREDS environment var to 'true', otherwise you get this disaster! Hahaha...ha."

Or if you don't know at the time what's going on, "obviously I'm just getting started on this myself, and need to play with some configuration. Better make sure I do before any of this goes to production! Hahaha...ha."
