I have an application where I am trying to implement google maps on angular app to show where the coordinates are on the map when the user selects a place. When I try to load this app i get the error. The HTML works fine but google map does not show on my app. It can be viewed on:

/

gMarker.key undefined and it is REQUIRED!!

Below is the code: HTML:

 <script src=",geometry,visualization&sensor=false&language=en&v=3.14"></script>
<script data-require="[email protected]" src=".2.16/angular.js" data-semver="1.2.16"></script>

<script src=".js/2.4.1/lodash.underscore.min.js"></script>
<script src=".js"></script>
<script src="controllers.js"></script>
</head>

<body ng-controller="mainCtrl">
<select ng-model="selectedCoordinate" ng-options="coordinate.caption for coordinate in coordinates">

</select>

<label>zoom</label>
<input type="number" ng-model="zoom"/>

<div id="map_canvas">
<google-map center="selectedCoordinate" zoom="zoom" draggable="true" options="options">
  <marker coords="selectedCoordinate"></marker>
</google-map>
</div>

I have provided head files as there have been errors due to the files before. How can I resolve this error?

Reset to default 10

I believe you're missing the idkey parameter on your marker directive.

<div id="map_canvas">
  <google-map center="selectedCoordinate" zoom="zoom" draggable="true" options="options">
    <marker idkey="{expression}" coords="selectedCoordinate"></marker>
  </gooogle-map>
</div>

This is new in version 1.2.0. You can read more about here.
