I am trying to use gapi to upload an image to google cloud storage.The current code I have is
<script src="https://apis.google.com/js/api.js"></script>
<script type="text/javascript">
var imgData = null;
function getImage() {
    navigator.camera.getPicture(onSuccess, onFailure, {
        destinationType: navigator.camera.DestinationType.FILE_URI,
        sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY
    });
    function onSuccess(imageURI) {
        imgData = encodeImageUri(imageURI);
        var contentLen = imgData.length;
        gapi.load('client', start);
    }
    function onFailure(message) {
        alert("Get image failed: " + message);
    }
}
function start() {
    // 2. Initialize the JavaScript client library.
    console.log('firing google storage api');
    gapi.client.init({
        'apiKey': 'XXX-XX'
    }).then(function() {
        // 3. Initialize and make the API request.
        console.log('api initialized');
        var request = gapi.client.request({
            'path': 'https://www.googleapis.com/upload/storage/v1/b/visionapibucket/o?uploadType=media&name=myObject',
            'method': 'POST',
            'headers': {
                'Content-Type': 'image/jpeg'
            },
            'body': imgData
        });
        try {
            //Execute the insert object request
            console.log('executing call');
            request.execute(function(resp) {
                alert(resp);
            });
        } catch (e) {
            console.log('An error has occurred: ' + e.message);
        }
    }).then(function(response) {
        console.log(response.result);
    }, function(reason) {
        console.log('Error: ' + reason.result.error.message);
    });
};
</script>
I can see that the code is hitting 
the statement in console is: api initialized
but I don't see the gapi.client.request being called or even printing any error etc.
I am not sure what is wrong here. Please advise
