TLS 启用 dgraph 服务器使用 c# StatusCode=Unavailable, Detail="Empty update" grpc 异常

问题描述

我正在尝试使用 c# .net 连接 启用 tls 的 dgraph 服务器，因为我在控制台应用程序下方编写了该服务器

class DGraphClient
    {
        public IDgraphClient GetDgraphClient()

                var tls = new SslCredentials(caCert,new KeyCertificatePair(clientCert,clientKey));

                client.Connect(GSioDgraph.Address,tls);



                //   var  result =  client.CheckVersion();


                return client;
            }
        }

并使用以下代码调用检查版本

 DGraphClient dc = new DGraphClient();
            try
            {
                var dgraphClient = dc.GetDgraphClient();


               
                var result1 = await dgraphClient.CheckVersion();

                if (result1.IsSuccess)
                {
                    Console.WriteLine("Connected to Dgraph version {Version}",result1.Value);

                }


                var res = await dgraphClient.Query(query);//.NewTransaction().Query(query);
                if (res.IsFailed)
                {
                    Console.WriteLine("ERROR THROWING");
                }
                result = res.Value;
                await dgraphClient.NewTransaction().Commit();
              
            }
            catch (Exception ex)
            {
                throw ex;

            }

在实例化客户端后，我只是检查服务器版本以确保其已连接但因 grpc {Result: IsSuccess='False',Reasons='ExceptionalError with Message='Status(StatusCode=Unavailable,Detail="Empty update")',Exception='Grpc.Core.RpcException: Status(StatusCode=Unavailable,Detail="Empty update")\r\n at DgraphDotNet.GRPCConnection.CheckVersion()\r\n at DgraphDotNet.DgraphClient.CheckVersion()'',} 失败
