"The parameter CNAME contains one or more parameters that are not valid" error message while deploying a CloudFront distribution

I'm getting this error message when trying to deploy a CloudFront distribution:

The parameter CNAME contains one or more parameters that are not valid. (Service: AmazonCloudFront; Status Code: 400; Error Code: InvalidArgument; Request ID: dfeb983d-b398-11e8-a2d5-5f6a8378e402)

I'm following the guide at http://templates.cloudonaut.io/en/stable/wordpress/#wordpress-fault-tolerant-and-scalable-mysql.

How can I fix this?

Make sure you do not have a blank entry in the Alternate domain name (CNAME) - optional section.

In other words, do not click Add Item and leave it blank. If you do and click save, it will think the blank entry is an alternate domain and give you the error: The parameter CNAME contains one or more parameters that are too small.

I investigated this issue by attempting to manually create the CloudFront distribution in the AWS console. When I pasted in the CNAME into "Settings / Alternate domain name (CNAME) - optional", it showed me the following warning:

Alternative domain name must contain one or more dots (.) and can only include lower case alphanumeric characters, dashes (-), and, optionally, a leading "*." to indicate all subdomains of the specified domain, for example, "*.example.com".

After I conformed my domain name to those requirements (i.e., converting to lowercase), the distribution deployed cleanly.

The parameter CNAME contains one or more parameters that are not valid is not a very helpful message — that should be improved!

For anyone else running into this issue, I ran into this issue today, and it turned out I had a misunderstanding about the HostedZone parameter in AWS's sample CloudFormation template - I had provided the Hosted Zone ID when the parameter was expecting the actual domain of the Hosted Zone. In this question's sample template, for example, the value of '${SubDomainNameWithDot}${HostedZoneName}' would need to be a valid domain name.
