I have a blueprint with a resource-assignment workflow for the AssignVnfBB.  It has a mapping file with the variable service-instance-id to accommodate the self-serve-vnf-ra-assignment DG in SDNC.  

I notice that if a use a jinja template, CDS silently fails to resolve the values and just returns the raw template to SNDC.   

The work-around is to use velotity template,  as dashes are not supported in jinja.
