I have managed to deploy my first skill using the Stanford calendar template from GitHub. I can see it in bothe the AWS Lambda console and the developer console and the skill and Lambda links look to be plumbed in at both ends ok. But when I go to the test page and type "Stanford Calendar" or "open stanford calendar " or any command in fact, it ust gives me a spinning response bubble. I've tried manually adding the Alexa Skill kit link to the Lambda fuinstion too. What am I missing?
