Node won't log the contents of a JSON Object, regardless of method

Question

I'm wrapping data to a Node.js WebSocket server in JSON. I'm trying to log the contents of the JSON object server side, but Regardless of the method I try, Node just logs object Object

I have tried

console.log(message.data)
console.log(util.inspect(message.data, {showHidden: true, depth: null}));
console.log(JSON.stringify(message.data));

Why would Node.js log object Object ? is the JSON malformed?

I'm sending VERY simple JSON objects from the client. Things like

ws.send({'a': 0, 'b': 1});

does it at least log null? if it doesn't log anything at all, chances are, it never got there. — chungtinhlakho

As stated in the question, it just logs "object Object" regardless of the log method. Now, if I try to log message.data.a it logs undefined — Native Coder

Yes, that's exactly what was happening. the client was converting the object literal. Look at @Dr Goat 's answer below.. — Native Coder

The client might be sending object Object, over the websocket, not the server being unable to parse the object. Try to stringify the object before you send it.

ws.send(JSON.stringify({'a': 0, 'b': 1})); //client

console.log(JSON.parse(message.data)); //server

GOOD CATCH! That's exactly what it was. I'll accept asap.

@NativeCoder Thanks, may I suggest using the rubber duck method, as it helps catch errors like this.

@NativeCoder You got him wrong. Just google rubber duck debugging, read the wiki and you'll get it.
