Cannot connect to Service through gRPC.

Expected Behavior

trying to use InvokeMethodAsync to call my rest based backend using grpc (it works using http://localhost:3500/v1.0/invoke/daprbackend/method/WeatherForecast)

Actual Behavior

When I call using gRPC I get the following exception “Error starting gRPC call: An error occurred while sending the request.” full logs: warn: Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer[100] Unhandled exception rendering component: Status(StatusCode=Internal, Detail=“Error starting gRPC call: An error occurred while sending the request.”) Grpc.Core.RpcException: Status(StatusCode=Internal, Detail=“Error starting gRPC call: An error occurred while sending the request.”) at Dapr.Client.DaprClientGrpc.MakeGrpcCallHandleError[TResponse](Func2 callFunc, CancellationToken cancellationToken) at Dapr.Client.DaprClientGrpc.MakeInvokeRequestAsync(String appId, String methodName, Any data, Dictionary2 metadata, CancellationToken cancellationToken) at Dapr.Client.DaprClientGrpc.InvokeMethodAsync[TResponse](String appId, String methodName, Dictionary`2 metadata, CancellationToken cancellationToken) at K8sFrontEnd.Pages.Counter.CallDaprBackendgRPCAsync() in /src/Pages/Counter.razor:line 63 at K8sFrontEnd.Pages.Counter.CallBothAsync() in /src/Pages/Counter.razor:line 71 at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task) at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle) Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer: Warning: Unhandled exception rendering component: Status(StatusCode=Internal, Detail=“Error starting gRPC call: An error occurred while sending the request.”)

Steps to Reproduce the Problem

1. have a service in k8s with the side car.
2. have another service with REST API and dapr side car.
3. invoke the backend microservice using the dapr Client with the following code:

var client = new DaprClientBuilder().Build();
var metaData = new Dictionary<string, string>();
metaData.Add("http.verb", "GET");
daprgRPCstring = await client.InvokeMethodAsync<string>("daprbackend", "WeatherForecast", metaData);

keeping it open till 0.6.0 is released if others stumble across this issue.
