Pahud, Thank you for your quick response! I had thought the pattern you suggested should work - however when I tried it I got an error, hence why I made...

I did also try: childARN := awsssm.StringParameter_FromStringParameterAttributes(stack, jsii.String("ARNFromKey"), &awsssm.StringParameterAttributes{ ParameterName: key, SimpleName: jsii.Bool(true), }).StringValue() In this case I get: deh-test-deploy-dev failed: ValidationError: Unable to fetch parameters [$.input.stateMachineArn] from parameter store...

I think this is the same as the issue: https://github.com/aws/aws-cdk/issues/6023 I was trying to find this again yesterday and only just discovered it

@pahud have you had a chance to see my comments above - The workflow I requested, does not seem to be supported, as my ARN is not known until runtime...
