I lunched gremlin-server 3.3.4 with neo4j 3.3.4 using http channelizer,
and it worked.
neo4j-empty.propertiesconfiguration was below

gremlin.graph=org.apache.tinkerpop.gremlin.neo4j.structure.Neo4jGraph
gremlin.neo4j.directory=/tmp/neo4j
gremlin.neo4j.conf.dbms.auto_index.nodes.enabled=true
gremlin.neo4j.conf.dbms.auto_index.relationships.enabled=true

but
1. http://localhost:8182/?gremlin=g.addV("test").property(id,"abc")
return error

"Exception-Class": "java.lang.UnsupportedOperationException",

and 2. I added vertex with multilabel http://localhost:8182/?gremlin=g.addV("test::test2") and query http://localhost:8182/?gremlin=g.V().hasLabel("test") return empty node

Neo4j does not allow id assignment. If you want to assign your own identifier then it needs to be a property like:

g.addV("test").property("id","abc")
