canFulfillIntentRequest "Skill endpoint returned an invalid response"

I've setup a new skill following this example skill for the canFulfillIntentRequest.

https://github.com/PaulCutsinger/Sample-For-Can-Fulfill-Intent-Request

I have enabled the required interface.

I'm using beta version of the SDK.

I've tested the skill using both the developer portal and the CLI tool.

I'm exposing the endpoint url using the Bespoken proxy so I can verify with the debugger.

I observed the following in my console output on my local machine.

The filled slots: {"voiceExpert":{"name":"voiceExpert","value":"Anna","resolutions":{"resolutionsPerAuthority":[{"authority":"amzn1.er-authority.echo-sdk.amzn1.ask.skill.54841bf0-1e88-4319-9dc7-ecbda6a98945.VOICE_EXPERTS","status":{"code":"ER_SUCCESS_MATCH"},"values":[{"value":{"name":"Anna Van Brookhoven","id":"dad826f08868120aa6e5e75a371e9b25"}}]}]},"confirmationStatus":"NONE"}}
in CFIR AboutIntentHandler {"voiceExpert":{"synonym":"Anna","value":"Anna Van Brookhoven","id":"dad826f08868120aa6e5e75a371e9b25","isValidated":true}}
in CFIR AboutIntentHandler YES

    }
  },

Using the developer portal I observed that the skill returned the following.

Hi and thank you for posting.

In order to test your skill against the CanFulfillIntentRequest, you need to send a JSON that simulates a request sent by Alexa.

Can you please share your JSON so I can take a better look at it?

Barry
