Connect to OrientDB using Gremlin.Net

Question

Hi I'm trying to connect to Orient.DB (Community 3.0.18) with gremlin support from a easy console application and Gremlin.net.

I'm using the standard demodb. I can't get any gremlin query run, I get:

ResponseException: ServerSerializationError: Error during serialization: Infinite recursion (StackOverflowError)

This is my code:

        var gremlinServer = new GremlinServer("localhost", 8182, enableSsl:false,  username: "root", password: "xxxx");

        using (var gremlinClient = new GremlinClient(gremlinServer, new GraphSON2Reader(), new GraphSON2Writer(), GremlinClient.GraphSON2MimeType))
        {
            var query  = "g.V(\"33:5\")";

            // Create async task to execute the Gremlin query.
            var resultSet = gremlinClient.SubmitAsync<dynamic>(query).Result;
            Console.WriteLine();
        }

I also tried GraphSON3Reader and GraphSON3Writer having the same result.

I have two big doubt:

1) How to let this work

2) How can I specify the database? for example on CosmosDB you have to specify it in the user parameter, I tried also this solutino but again no luck.
