Some more information.
I removed my plugin list and started to add them back in one by one. It turns out that everything works fine until I add the com.google.cordova.admob plugin. Once I have that in there I get the above error.
This plugin was working fine before. The only changes I can think of that I’ve made are related to UI and a few controller js changes.
I am going to run some tests around fresh projects using only this plugin to see if there are any conflicts.
