Google Maps API: Uncaught TypeError: Cannot read property '__e3_' of undefined

Question

I'm currently use a new system for my weather website and I'm getting the following error:

Uncaught TypeError: Cannot read property '__e3_' of undefined

        } else {
            alert('Det gick inte att hitta höjdskillnaden på grund av följande: ' + status);
        }
    });
}

The problem is that the system is quite the same as in my previous system and I have the same "code structure" on both of them and still I'm getting this error message on the new system. I don't know why I'm getting it so I'm asking you know: how can I fix my problem?

Thanks in advance.

Answer 1

When I moved the map definition to a point before the marked buggy code, it worked. I added the var map = new google.map.Map to right after the map options.

  var myOptions = {
     streetViewControl: false,
     overviewMapControl: true,
    zoom: 14,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};

var map = new google.maps.Map(document.getElementById('weather-map'), myOptions);

// MOLNAKTIVITET
var cloudLayer = new google.maps.weather.CloudLayer();
cloudLayer.setMap(map);



/**********************************************
**    THE CODE BELOW IS CAUSING THE ERROR    **

// HÖJD ÖVER / UNDER HAVSYTAN
elevator = new google.maps.ElevationService();
google.maps.event.addListener(map, 'click', getElevation);
