I keep getting Exception in template helper: TypeError: Cannot read property 'coords' of null when first calling geolocation

help
1 
        var fromLat = Geolocation.currentLocation().coords.latitude;
        var fromLng = Geolocation.currentLocation().coords.longitude;

debug.js:41 Exception in template helper: TypeError: Cannot read property 'coords' of null
    at Object.Template.home.helpers.images (http://127.0.0.1:3000/app/client/templates/home/home.js?3e020770d01e841360fd1115d63b6042e3dfdf68:25:48)

But, it is only once when the page loads. after that it seems okay. any help would be cool

well, it is regarding this line Geolocation.currentLocation().coords.latitude

and yes, Geolocation.currentLocation() can be null before proper initialization

well, Geolocation object is not part of the core, so maybe consult readme to given package
