How to debug these Dev Tools errors?

I am getting lots of error like this in Dev Tools in a couple different apps:

They show up as I am moving the mouse around the app and I can't figure out where the bug is! I assume it is in my JS code somewhere but I can't find it. It is not obvious like "Click button 1 and error pops up" - they are apparently randomly generated.

Any advice on how to proceed?

Hey @bradlymathews! Thanks for surfacing this, it looks like it's showing up for others as well and may be a bug on our end. Are you noticing it in any apps in particular? Can you trigger it by hovering over code or prompting auto-complete?

Ahhh, Yes and Yes!

I am also using the Beta code editor.

Ok, thanks for confirming! I've surfaced this with the dev team. Are you noticing anything failing?

No failures. :smiley: The new code editor still needs some polish and maybe that is just sitting on the other side of the error.

And just a tad annoying while debugging js code.

Hey @bradlymathews! This should now be fixed - can you let me know if you're still having the same issue?
