I was successfully able to follow this tutorial Tutorial: Creating a Service Instance from a Design Model to create a service instance. But after some time the VID was unable to fetch the suscribers from AAI. The VId logs show some error in AAI. The AAI rest logs show a NullPointerException. 

VID logs: /opt/app/vid/logs/vid/error.log

      Deleting the aai-service docker container and recreating it fixes the issue. I'll leave this quesiton open for a while until I sure that this problem won't occur again.
