I'm very new to Alexa Skills, and just finished connecting Alexa skill Interaction Model and the Lambda function on AWS.
I set up a simple node.js program on AWS lambda developer console, and I'm testing it on the AWS console using their test function. But I can't figure out why this is giving me an error. Also, I created this project from the sample repo - serverlessrepo-alexa-skil-alexaskillskitnodejsfact

It looks like the Alexa.getRequestType is not defined. Is there anything I'm missing in this process?
Thanks!
