[Help] API keeps crashing w/ error: "TypeError: Cannot read property of 'get' of undefined

This sounds kind of generic so I'm not sure where to begin troubleshooting. I noticed it after spending a couple hours building maps, drawing dynamic lighting, and making some new sheets/tokens. Any help as to where to begin testing/debugging would be much appreciated.

My game is as follows
:
  • 5e Shaped v7.1.x
  • Scripts installed include: 5e Companion; TokenMod; TrakcerJacker; Aura; TableExporter; GroupInitiative; AoE
The full log from the API page is:
For reference, the error message generated was: TypeError: Cannot read property 'get' of undefined

It's definitely crashing in the Shaped Companion Script.  Not sure what the problem actually is.  What did you do just prior to it crashing?
Don't know at what point it actually crashed. Just prior to noticing the API wasn't running I had created a new token and assigned it to a character sheet, then ran !shaped-apply-defaults. Only thing different was I was assigning the new token to represent the same sheet as other tokens (a named boss version of the "Orc" sheet.

If you can figure out the steps to reproduce it, I'm sure Lucian would appreciate it.

Just posting that stack in the Shaped Companion thread might yield a response about an own bug you can avoid.

I'll see if I can narrow down the circumstances and post in the Companion thread. Thanks.

Hey Andy. I've had problems with the Aura script crashing the API, giving that error. But I haven't been able to pin down exactly what causes the problem.

I have a modified version of the aura script that seems to be more stable, though has a lesser functionality. It does still creates the health colour around the tokens. None of this is mine, I just deleted bits from the original. Full credit to DXWarlock for making my favourite script!

Thanks Kirsty! I'll give that a try if this error persists. Can you tell me what functionality was lost?
