I cannot create a custom marker. Even though I am passing an image path to the icon parameter I am still getting the default orange marker. Please tell me if you see anything wrong.
Directive's template:
<div id="searchMap" class="googleMaps-destinations">
<div class="google-maps">
    <ui-gmap-google-map center="map.center" zoom="map.zoom" options="map.options">
        <ui-gmap-marker 
            ng-repeat="marker in search.origin_airports" 
            coords="marker.originMarker.location" 
            icon="marker.originMarker.icon.url" 
            fit="false" 
            idkey="'<< marker.originMarker.id >>'" >
        </ui-gmap-marker>
    </ui-gmap-google-map>
</div>
I am using : //maps.googleapis.com/maps/api/js?v=3&sensor=true with angular-google-maps/dist/angular-google-maps.js
