AWS Lambda with SAM Template to subscribe an SQS to an SNS Topic.

This block diagram describes an SNS Topic that has an SQS Subscription and a Lambda that fires off when a message is received by the SQS Queue. If you are like me, you created a simple SAM Template that defined the Lambda AWS::Serverless::Function definition that has an SQS Queue as its event source. While that is most of the solution you would find that messages never flow into your SQS Queue. You refresh the console and there are always zero messages.
