My app is no longer working and it appears to be from changes in the handlerInput response JSON.
I used to be able to grab the accessToken via:
handlerInput.requestEnvelope.session.user.accessToken;
But now it does not seem to be there. It appears that instead there is a block called "permissions" with a consentToken in place? That is not the same thing for me though. Is there any documentation on these breaking changes?
