This error occurs when you need to pass in a parameter to a CloudFormation template and one is not supplied or it is supplied incorrectly.

In my case I created a script to deploy my CloudFormation template and passed in a parameter like this:

suffix="POC"
./deploy.sh $suffix

The problem was that I had named my parameter in my CloudFormation template:

something different from the name I was passing into from my deployment script:

Once I corrected the parameter name, my script worked.
