32600 - Invalid request about jayson

[raskyer]

I found out what should I specify in my request like =

{"jsonrpc":"2.0", "method":"add", "params":[10,10]}

But now I got an other problem. (I try using telnet). When I send this with telnet I can't have an answer from the server (basically 10 + 10 result in this example). But callback seem to be a valid function when I console.log it...

Okay really sorry @tedeh I'm starting to understand.

On the server/index.js we got those lines =>

 var respond = function(error, result) {
      if(utils.Request.isNotification(request)) return callback();
      var response = utils.response(error, result, request.id, self.options.version);
      if(response.error) callback(response);
      else callback(null, response);
    };

It seems that when I call the server with the former parameter I mention, the first if is activate =>

 if(utils.Request.isNotification(request)) return callback();

Because callback() has no argument it's an undefined response sent. If I comment this line. Everything seems fine and I got the excepted answer :

{"jsonrpc":"2.0","id":null,"result":20}

Ok I understand it by looking at utils.isNotification, I need an "id" to get the answer.
Thanks !

He he, yes, you need an ID or your request is considered a notification, which means that it does not expect a response.
