rpc错误：代码=内部错误 描述=grpc：解组时出错：proto：无法解析无效的线格式数据

解决方案

1. 90% 成功率 Ensure both client and server use the same protobuf version and schema.

   Run 'protoc --go_out=. --go-grpc_out=. *.proto' on both sides and rebuild.

2. 70% 成功率 Add logging to inspect the raw bytes received.

   Use a server interceptor to log incoming data for debugging:
   func loggingInterceptor(ctx context.Context, req interface{}, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (interface{}, error) {
       log.Printf("request: %v", req)
       return handler(ctx, req)
   }
