Issue # (if applicable)
Closes #29424.
Reason for this change
Stack tags get applied to every resource they contain. Tokens must be resolved by CloudFormation itself and the CDK CLI has to apply stack tags to the stack before the deployment starts. This results in the string representation of the token (eg
Token[AWS.AccountId.6]) making its way into the stack tags. CFN applies these tags automatically to every resource, but this string value contains characters that many resource handlers do not allow in tags. This causes a deployment error.Description of changes
Move this error to synthesis time by checking for tokens before adding the tags.
Description of how you validated changes
Unit tests.
