Great tutorial - very clear compared to some others I saw and this got my lambda function operating in a VPC as desired. One issue I had though is if the Lambda function has an Amazon Alexa Smart Skill as a trigger, is there something I need to configure in the VPC for this to work? Alexa skill can access the lambda function when it is not using a VPC but when I use the VPC, the smart skill cannot access the Lambda function's ARN.
