Hello @DALDE_John
I’ve tried to reproduce it, but I couldn’t. Can you create a minimal reproducible example and share app id where you created it.
Regards, Dima
Here’s a link of the method https://api.backendless.com/4A47197B-AE30-FA84-FF56-0071F4010900/A39AC69D-C148-48A3-BDCE-0821C4698217/services/BG_01_ADMIN/sandboxAustin
and here’s the app id 4A47197B-AE30-FA84-FF56-0071F4010900
I think the error located here:

_cacheChecker is undefined
Also, the update goes through but it returns that particular error.
As I see in logs, errors returns from the event handler weekly_slots afterUpdate. Could you check it?
Thank you it was because of a Save Object block
