ServiceInvocation service is used to exchange the data between caller dapr runtime and callee dapr runtime. The request message includes caller's HTTP/gRPC request and deliver callee's response including status code. The response status of rpc methods represents of internal gRPC connection status, not callee's response status. Thus, ServiceInvocation gRPC response returns OK in most cases regardless of callee's response.
