In the yaml file determining class Settings you use the channelizer key twice. If you use ConfigurationManagentGraph only the following line should be present: channelizer: org.janusgraph.channelizers.JanusGraphWebSocketChannelizer
Does that make any difference? Does stil the part ¨with one argument of class Settings,¨ show up in the ERROR message then?
