AWS::UrlSuffix pseudo parameter is not recognized by rule E1019

See original GitHub issue

cfn-lint version: 0.26.3

I am attempting to use a Fn::Sub with the following arguments: https://s3.${AWS::Region}.${AWS::UrlSuffix}/amazoncloudwatch-agent-${AWS::Region}/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm and I am recieving the following error:

E1019 Parameter AWS::UrlSuffix for Fn::Sub not found at Resources/LaunchTemplate/Metadata/AWS::CloudFormation::Init/SharedConfig/files//tmp/amazon-cloudwatch-agent.rpm/source/Fn::Sub
build/sam/template.yml:6178:17

It appears that this rule is too strict or is not aware of the new ${AWS::UrlSuffix} pseudo-parameter. See the Pseudo Parameter docs for more detail.

Looks like that is how CloudFormation handles it too.
Unresolved resource dependencies [AWS::UrlSuffix] in the Resources block of the template

@kddejong FWIW, CFN to my knowledge has always supported using pseudo parameters in a Fn::Sub. The doc you mentioned gives examples for just two of the pseudo-parameters but doesn’t preclude any others though.
