  • Hello Narendra,

    Based on the experiment that was used to deploy this web service it looks like the train module might have generated this error. A good way to debug the same would be to enable logs on your web service from the configure section of your web services dashboard and run a new request. The logs would be available in the storage container that is configured for your ML workspace. 

    Also, Could you please check the service swagger document for the input parameters that are required and provide all the inputs while testing? To get the swagger document you can follow the steps mentioned below to view the document.

    1. Click Consume tab from the web services dashboard.
    2. On the Consume page, copy the Request-Response URL.
    3. In the URL, replace execute?api-version=2.0&format=swagger with swagger.json
    4. Paste the URL into your browser to view the swagger JSON file.
