When you have libraries loaded at a global level the debug tools do not take this into account and report problems for undefined functions etc even though at run time it works fine. This also happens if you define the library at the app level rather than global level.
Hey @alec-hs! Ah, great callout. I filed this internally with the team building our debug tools—will post here with any updates
This has been fixed! The fix should go live with our next deploy, which is generally in the middle of each week Thank you for surfacing this, @alec-hs
