Thank you everyone for your quick responses! I've added the modified version of Draggable like you suggested. When I click, my element moves, once, then this same error fires, but on a different line in Cordova (see attached image).
Seems to be something with the "onPress" method. I tried rolling back to GSAP version 1.19.1 and these errors go away, even without the update to Draggable. That version doesn't have the same rotationOrigin that the latest 1.20 version has, so I can't implement the nice rotate to clicked point feature.
Thats really what I'm trying to get working. Any ideas on that? Is it possible to wire up the rotationOrigin a different way on version 1.19.1?
Note: I can't make any lasting changes to cordova.js. It always fixes itself.
