Cannot remove devices -- Error: Cannot invoke method removeChildFromSettings() on null object

I’m trying to remove devices from the developer site and keep getting this error:

Cannot invoke method removeChildFromSettings() on null object

I’ve also tried removing via the Android app to no avail. Any ideas?

You’re most likely getting that error because you’re trying to delete a device that is a child of a SmartApp.
