When I try to invoke PlaybackController interface intents (using the alexa mobile app audio player next/previous/play/pause buttons),my skill gets mapped to my Unhandled intent. This is the request that gets sent to Unhandled:{"type":"PlaybackController.
PlayCommandIssued","requestId":"amzn1.echo-api.request.bfa1ec0d-db7f-4d49-b037-674ebecf8851", and "timestamp":"2018-10-09T21:32:41Z","locale":"en-US"}
I thought maybe this was because I didn't include them in my interaction model, but they are not allowed to be added to the interaction model:Build Failed
Intent name "PlaybackController.
PlayCommandIssued" contains invalid characters. Intent names must start with an alphabetic character and may only contain alphabets, and periods,and underscores. Error code: InvalidIntentName
I don't bear a device with a screen to test further besides the alexa mobile application. My regular AMAZON.
NextIntent and AMAZON.
PreviousIntent work fine using voice commands.
