Task: Troubleshooting a CloudFormation stack failing due to a Property validation failure

While working on an EKS with Fargate Game Build project linked here, at one point I was having problems with the design and execution of the build, so I switched tactics and attempted the same build using Cloud9. During the deployment of the Cloud9 infrastructure, I ran into an issue and thought I would share it.
