Description
If I configured gremlin-server.yaml with
serializers:
- { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerGremlinV1d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistryV1d0] } } # application/vnd.gremlin-v1.0+json
And configure a remote client like so
conf/remote.properties:
gremlin.remote.remoteConnectionClass=org.apache.tinkerpop.gremlin.driver.remote.DriverRemoteConnection
gremlin.remote.driver.clusterFile=conf/remote.yaml
gremlin.remote.driver.sourceName=g
conf/remote.yaml:
hosts: [localhost]
port: 8182
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerGremlinV1d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistryV1d0] } }
Then I connect with the client and get this error:
gremlin> graph = EmptyGraph.instance(); g = graph.traversal().withRemote('conf/remote.properties')
==>graphtraversalsource[emptygraph[empty], standard]
gremlin> g.V()

It works when using v2.
