Passing a String as radius makes entire app crash (Ionic)

[johnrobertcobbold]

When passing an array to window.geofence.addOrUpdate, I did not realise that some of the geofences to be created had their radius set as a string. This makes my entire app (Ionic) close without any error being returned. I understand that Number should be used as radius but I guess checking on the variable type and raising an error if necessary might be helpful ?
