Thanks for the report @lucasdauto! We'll look into this next week (:

This is odd. From what I can tell, text is guaranteed to be a string. In fact, we even check for a falsy value or empty string and ensue it's a non empty string here: https://github.com/facebook-atom/atom-ide-ui/blob/master/modules/atom-ide-ui/pkg/atom-ide-console/lib/ui/RecordView.js#L94

I guess that means that text must be both truthy and not a string. I don't immediately see how that could be the case.

I ran into this issue as well. I caused it by calling console.error(anExceptionObject) (pseudocode), and seeing how it'd come out. anExceptionObject would be truthy and not a string. I should have done console.error(anExceptionObject.toString(). log and friends expect a string input. This was mostly caused on my end by not looking at the expected types, but the note about only allowing string or falsey input wasn't in the formal documentation.
