Can't use instance of graph management

Question

I connect to gremlin-server from gremlin console with this configuration:

connect_config.yaml

hosts: [XXX.XXX.XXX.XXX]
port: XXXX
serializer: {
  className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0,
  config: {
    serializeResultToString: true,
    ioRegistries: [org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry]
  }
}

when i run method graph.openManagement() it will ok

gremlin> graph.openManagement()
==>org.janusgraph.graphdb.database.management.ManagementSystem@392e7533

but when i try save reference to management object and use it i get error:

gremlin> m=graph.openManagement()
==>org.janusgraph.graphdb.database.management.ManagementSystem@326fbc0a
gremlin> m.commit()
No such property: m for class: Script8
Type ':help' or ':h' for help.

What is this error, and what i must do to fix it?

Answer 1

I assume the problem is that you are not using a session in Gremlin Console:

:remote connect tinkerpop.server connect_config session
