I’m trying to test my first skill in the Developer Console. The skill was successfully built after removing all coding errors flagged-up in the Code section. This skill is supposed to play audio tracks from an xml file in root director of my web site. URLs seem to be OK. I’m using the Alexa Simulator: language set UK, but the “open (skill name)” invocation gets an “I don’t know that one” response. Skill name meets the criteria. I’m obviously making a basic mistake as I’ve not done this before. Any pointers please?
