Future versions of the Alexa Skills Kit may add new properties to the JSON request and response formats, while maintaining backward compatibility for the existing properties. When we invoke the skill with additional parameters, the skill is rejecting it when we expect this to be accepted. Your code must be resilient to these types of changes.

Future versions of the Alexa Skills Kit may add new properties to the JSON request and response formats, while maintaining backward compatibility for the existing properties. When we invoke the skill with additional parameters, the skill is rejecting it when we expect this to be accepted. Your code must be resilient to these types of changes.
For example, your code for de-serializing a JSON request must not break when it encounters a new, unknown property. Please see the following documentation for more information: https://developer.amazon.com/appsandservices/solutions/alexa/alexa-skills-kit/docs/alexa-skills-kit-interface-reference
