When using a service such as the one from the service template attached, a NPE is generated as below. Looks like something in the TOSCA parsing is hardcoded to look for VNF.

This only happens when using the serviceSpecification on a specific Id (which then triggers the logic to identify the udnerlying resources), the find works fine.

As a side effect, the inventory API is also impacted when trying to fetch the serviceSpecName or serviceSpecId if only one of the 2 is specified in the query.
