Encountered an error when making Gremlin.Net communicate with JanusGraph in the JanusGraph official website.net introductory tutorial

I tried to operate JanusGraph with .net using JanusGraph official tutorial, but got an error, the following is my code and .net\JanusGraph Error displayed by the server

I use vscode, the command to create a project is dotnet new console -o GremlinExample

Looks like I haven't added what I'm asking, but chatGPT thinks it's a result of neither the server nor the client getting the response they need, so I doubt it's something wrong with Gremlin.Net... ...

code：

using Gremlin.Net.Driver;
using Gremlin.Net.Driver.Remote;
using static Gremlin.Net.Process.Traversal.AnonymousTraversalSource;


Console.WriteLine("Hello, World!");


var client = new GremlinClient(new GremlinServer("localhost", 8182));
// The client should be disposed on shut down to release resources
// and to close open connections with client.Dispose()
var g = Traversal().WithRemote(new DriverRemoteConnection(client));
        // Reuse 'g' across the application

Console.WriteLine("d!");

var herculesAge = g.V().Has("name", "hercules").Values<int>("age").Next();
Console.WriteLine($"Hercules is {herculesAge} years old.");

.net terminal:

PS C:\Users\Win10\GremlinExample> dotnet run
Hello, World!
d!

Solution

  • run

     dotnet add package Gremlin.Net

    instead of

    dotnet add package Gremlin.Net -v 3.5.5

    to upgrade Gremlin.Net to the latest version, now the problem has been alleviated

    Or use this method

    var client = new GremlinClient(new GremlinServer("localhost", 8182), new GraphBinaryMessageSerializer(JanusGraphTypeSerializerRegistry.Instance));
var g = Traversal().WithRemote(new DriverRemoteConnection(client));
