Create a TOSCA using Simple profile.

Add a 'Groups' element to the main definition template with type 'org.openecomp.groups.VfModule'. This maps to the VFModule object.

Onboard the csar and check the onboarded csar by downloading it from the UI.

The onboarding process removes the 'Group' element.

 The expectation is that SDC should retain the group element and add its metadata to it. (modelid, etc).

Consequently, the TOSCA that gets distributed, also does not have this element and it fails in SO.

The example csar is attached

 vfw_vfModule.csar
