Stack error: 1 HutongGames.PlayMaker.Fsm:Update()

[Christoph]

With my latest update I get this error more and more from my players. No idea where it comes from. It shows up in my Analytics tools like GA and Firebase Crashlytics.

The error says only:
Stack error: 1 HutongGames.PlayMaker.Fsm:Update()

How to track this down? How to solve? I guess this crashes the users device?

Any help is appreciated.

From Firebase it’s a bit more extended. But still no clue:

Non-fatal Exception: java.lang.Exception: InvalidOperationException : Stack empty.
       at System.Collections.Generic.Stack`1[T].ThrowForEmptyStack(System.Collections.Generic.Stack`1[T])
       at System.Collections.Generic.Stack`1[T].Pop(System.Collections.Generic.Stack`1[T])
       at HutongGames.PlayMaker.Fsm.Update(HutongGames.PlayMaker.Fsm)

Thanks for the error message, it's a good starting point. I'll investigate and get either a fix or a better error message into the next update.

Thing is I can't replicate it on my end. Not even sure where to look tbh.

Hi,
I have encountered stack error multiple times, all where after changing a template used with Run Fsm action in other fsm's.
if you click on the error does it point to an object?

Hi djaydino, the error is not happening in the console/Unity editor. It happens in the live version on the store, respectively on end-users devices. I see the error log in Firebase and GameAnalytics.
