we have a workaround for this issue, we put service csar as artifact file which you can refer to ns.csar. We have to keep the VNF ID in VNF the same as the VNF ID in NS. I have define VNF ID vCPE_Infrastructure_BGREMU_demo_app
, vCPE_Infrastructure_GW_demo_app, vCPE_Infrastructure_vGMUX_demo_app, vCPE_Infrastructure_demo_app, vCPE_Infrastructure_Metro_vBNG_demo_app).

I have onboarded vsn.csar into SDC, and exported service-VsnSer-csar.csar. The onboarding csar have been verified successfully by VFC, however, the exported csar causes errors in VFC's tosca parser:

 unap@hnud:~/tst$ tosca-parser --template-file service-VsnSer-csar.csar

The findings are:

1. The error "MissingRequiredFieldError: Data value of type "org.openecomp.datatypes.Naming" is missing required field "['supplemental_data']"." is caused by the following data type definitions in the file 'data.yml' in the exported csar package:

            org.openecomp.datatypes.Root:
               derived_from: tosca.datatypes.Root
               description: The ECOMP root Data Type all other Data Types derive from
               properties:
                   supplemental_data:
                   type: map
                   entry_schema:
                       description: A placeholder for missing properties that would be included in future ecomp model versions. fromat <key>:<value>
                       type: string

         SDC doesn't mark the supplemental_data property of data type org.openecomp.datatypes.Root as 'required:false', so VFC's tosca parser complains the missing property.

     2. For the annotation_type, it's an SDC's own extension to TOSCA spec, and it assumes the standard tosca parsers will ignore the annotations(https://wiki.onap.org/display/DW/4.3.7.+Annotation+Types)
