Alright - So I've built my skill out, interaction model, all that jazz. When testing via the API or via echosim.io - works fine. Not an issue, launch, intent, all good. I get the responses I'm looking for.
When I try to execute it on my hardware Echo, however - I get nothing. I have enabled the device in Dev mode, and I can see the skill in my list. Attempts to launch either straight end the interaction, or I get a vague message of sorry. I look at the history, and the commands are recognized word for word, it just isn't executing. Extremely odd when doing it with EchoSim at the same time, watching ES execute correctly, and the hardware fail.
I've been bashing my head against this for awhile now - and can't find anything about what's causing this exact issue. Lots of malformed requests, missing responses, etc. Anyone have any idea how to solve this? I can't imagine this is just a 'problem' that the device has, otherwise it wouldn't be successful.
