  • a is null or not an object
  • oa is null or not an object
  • ‘J’ is null or not an object

The error is exactly what it says – you are probably adding or removing a null overlay.

The Fix for this is to do an if statement to check if your overlay is null before you try to add or remove it = 

if ( myOverlay != null )
	map.removeOverlay(myOverlay);
