After clicking anywhere on the base map I get an error in console saying
Uncaught TypeError: Cannot read property 'position' of undefined

I have a MapView.on('click',callback()) attached to the mapview however even after I comment out this entire code block I still get the error when clicking anywhere on the base map.
