我是 Dgraph 的新手，我正在使用 .NET Core C# 客户端（https://github.com/MichaelJCompton/Dgraph-dotnet 1）连接 Dgraph 服务器、查询和变异数据。

我面临这个问题：

{
  ExceptionalError with Message='Status(StatusCode=ResourceExhausted,  
  Detail="received trailing metadata size exceeds limit")',  
  Exception='Grpc.Core.RpcException: Status(StatusCode=ResourceExhausted, Detail="received trailing metadata size exceeds limit") at  
  DgraphDotNet.GRPCConnection.Query(Request req) at  
  DgraphDotNet.DgraphClient.Query(Request req) at  
  DgraphDotNet.Transactions.Transaction.QueryWithVars(String queryString, Dictionary`2 varMap)'
}

GRPC 选项

var server = "xxxxx";
       CurrentClient.Connect(server, ChannelCredentials.Insecure, new[]{
        new ChannelOption(ChannelOptions.MaxSendMessageLength ,2147483647),
        new ChannelOption(ChannelOptions.MaxReceiveMessageLength , 2147483647)
  });

程序.cs

services.AddGrpc().AddServiceOptions<DgraphDotNet.IDgraphClient>(options => {
       options.EnableDetailedErrors = true;
       options.ReceiveMaxMessageSize = 2147483647;
       options.SendMaxMessageSize = 2147483647;
    });

但仍然面临这个问题。附加：我调试到最终的 GRPC 调用

CallInvoker.AsyncUnaryCall(__Method_Query, null, options, request);

并看到这样的参数
