Description of changes:
#842 was made with the assumption that in the Smithy model, the strings that need Fn::Sub contain the final values as CloudFormation expects. It did not consider that those string could contain placeholder literals, like
<lambdaFunction>
or{{REPLACEME}}
that could be post-processed by something like the CDK to generate the values as CloudFormation expects.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
