Cannot read property 'lat' of undefined

[scottfister]

Hi! I found an issue similar to mine that was closed, reporting the same error: Uncaught TypeError: Cannot read property 'lat' of undefined on helpers.js:197: return helpers.makeObj(latKey || 'lat', val.lat(), lngKey || 'lng', val.lng());. But I confirmed I was doing all the appropriate things and it still doesn't seem to work.

I'm running Ember v1.13.4 and Ember Data v1.13.5.

Template: {{google-map markers=model markerController='map/service-marker'}} Note: I also tried model.content and the error isn't thrown but no pins are placed.

Route:

...
model: function() {
  return Ember.A([
      {name: "Home", latitude: 14.766127, longitude: 102.810987, body: "Here is B&H's home"},
      {name: "Shop", latitude: 14.762963, longitude: 102.812285, body: "Here is B&H's shop", isInfoWindowVisible: true},
      {name: "Hay's", latitude: 14.762900, longitude: 102.812018, body: "Here is Hay's shop"}
    ]);
}
...

controllers/map/service-marker.js

...
lat: Ember.computed.alias('latitude'),
lng: Ember.computed.alias('longitude')
...

I also tried setting the aliases directly on the models to no avail. I have to use this for a project due in a day, if anyone can assist I'd really appreciate it.
