Hi, most likely it is caused by using wrong version of the core library package. Some parts of it are written in Python rather than in MuranoPL and located inside murano source codes. So if you use newer version of core library with older version of Murano you get this error. In particular it cannot find https://github.com/openstack/murano/blob/stable/mitaka/murano/engine/system/net_explorer.py#L195 method which is available since mitaka.
