Display Error on device.

For a skill with images, images are showing up when testing in amazon developers console. But when i test this same skill in echo show. It just shows up the title, No image is displayed.

The code for my display function is as :

function initiateImage(imageSrc){
    const title = 'Game';
    const image = new Alexa.ImageHelper()
      .withDescription('alexa')
      .addImageInstance(imageSrc)
      .getImage();

    const template = {
        type: 'BodyTemplate1',
        backButton: 'HIDDEN',
        title,
        backgroundImage: image,
    };
    return template
}

And inside my handler is as:

const LaunchRequestHandler = {
    canHandle(handlerInput) {
        return handlerInput.requestEnvelope.request.type === `LaunchRequest`;
    },
    handle(handlerInput) {
        const imageSrc1 = 'https://ballypics.s3.amazonaws.com/page-3-ballicopter~ipad.png';
        var temp=initiateImage(imageSrc1);

        return handlerInput.responseBuild
          .addRenderTemplateDirective(temp)
          .speak(welcomeaudio)
          .reprompt(helpMessage)
          .getResponse();
    },
};

Please help with this. Do I need to make any changes in the code or image specifications? I have hosted my images in S3 with public access and already changed the policy for CORS. Thanks
