Failed To Save Application Data - Why?

I’m getting the subject error when trying to save my app. I have added a dropdown and built its contents with the MAP() function. How do I track down the problem? What’s the troubleshooting process like?

This bug will be fixed in the next release (hopefully next week), sorry for the inconvenience! Ticket to follow, also with instructions on how to circumvent this at https://tracker.appgyver.com/bug-reports/p/switching-a-static-array-binding-to-a-formula-causes-failed-to-save-application
