In the createCustomE2EServiceInstance BPMN flow's subflow doCreateResources, it is using serviceModelName to find the vnf_recipe in order to instantiate the resources. Vnf_recipe does not contain a serviceModelName column in the database, instead it is comparing against the NF-Role column. This will never work unless the serviceModelName is identical to the NF-Role property, which is a non-required free-text field when designing service.
