cfn_template,err := goformation.ParseYAML([]byte(SournceYaml))

fmt.Println(string(strYaml))

Output:

is missing goformation is not able to set the reference.

The same goes for properties when setting a value in properties and referring the same it is not working.
these are valid when we want to set a VPCid for a stack and need to refer the same from the resources.

@community if this change is fine can we look for other referencing issues for e.g., GroupId for SecurityGroupIngress?
