Question

anyone can help me?
when i config janusgraoh factory as instruction,
but i can ConfiguredGraphFactory.createConfiguration(new MapConfiguration(map));
i can not open graph:ConfiguredGraphFactory.open("graph1")
this is gremlin.yaml

graphManager: org.janusgraph.graphdb.management.JanusGraphManager

this is janusproperties:

Your configuration file for the server is not a valid YAML file as it's incomplete. It should look something like this:
