Error in Upload Asset Action. Create Asset Servlet called with format=json AEM 6.2

[#1]

Has anyone faced this issue - 

Inside Asset Share page, on using the Upload Asset Action component, it throws this error - Error: SyntaxError: Unexpected token < in JSON at position 72

On looking at this further, it posts the request to http://server:port/content/dam/sample.createasset.html?format=json

and though the upload is happening successfully, the json response from the CreateAssetServlet is malformed, ie html gets appended to the json response.

Please see the screenshot..

Hi 

Moving this thread to AEM "Asstes" topic so to have better contextual experts have a look at this.
