I can't create an edge in aws neptune using gremlin. I can create vertices. but not edge.
import { driver, process as gremlinProcess, structure } from "gremlin";
async function checkOut() {
const DriverRemoteConnection = driver.DriverRemoteConnection;
const Graph = structure.Graph;
const dc = new DriverRemoteConnection(
ws://localhost:7070/gremlin, {
sloppy: true,
rejectUnauthorized: false,
});
const traversal = gremlinProcess.AnonymousTraversalSource.traversal();
const _ = gremlinProcess.traversal();
const graph = new Graph();
const g = graph.traversal().withRemote(dc);
const v1 = await g.addV("person").property("name", "main").next();
const v2 = await g.addV("person").property("name", "male").next();
const data = await g.addE("wrote").from(g.V(v1.value.id)).to(g.V(11)).next();
g.V()
.toList()
.then((data) => {
console.log("DATA", data);
dc.close();
})
.catch((error) => {
console.log("ERROR", error);
dc.close();
});
}
checkOut();Solution

g.V(11) is not valid query for Neptune, vertex id should be string value https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-differences.html#feature-gremlin-differences-vertex-edge-idsGremlin standards compliance in Amazon Neptune - Amazon Neptune
Overview of differences between the Neptune and TinkerPop implementations of Gremlin.
Apache TinkerPop is an open source graph computing framework and the home of the Gremlin graph query language.
