Seeing "[object Object]" when calling any flow variable from NodeJs script

[kotikarthickkum]

Here is my code snippet

var express = require('express');
var usergrid = require('usergrid');
var config = require('./config');
var apigee = require('apigee-access');
var http = require('http');


var app = express();


app.post('/', function(req, res) {
	console.log("inside post");
  	if (!req.is('json')) {
		res.jsonp(400, {
			error : 'Invalid Request payload Type. Please make sure Content-Type header is JSON'
		});
		return;
	}
	console.log("request: "+req);
	var b;
    try {
	console.log("retrieving req body");
      b = req.body;
	  	console.log("retrieving req body done");
    } 
...

Trace Record:

stdout  svr.358  retrieving req body done
stdout  svr.358  retrieving req body
stdout  svr.358  request: [object Object]
stdout  svr.358  inside post

Hi Karthick

that does not look like an error to me.

In JavaScript, when you implicitly convert an object to a string , you will get "[object Object]". It's coming from the line where you try to print out the request. (I guess you knew that). So the behavior you report is correct, and expected.

But I guess that console.log() call is an attempt to diagnose or debug some other problem.

What problem are you REALLY trying to solve?

Also, you mentioned something about a "flow variable" but I don't see any attempt to access flow variables in your code.

Hi Dino,

Thanks for that. I was not aware of this - you will get "[object Object]".

I could sort out the flow variable problem. I am trying to access the variable that gets created through a OAuth policy(Validate) but I am trying to access that through a service callout and hence the problem.

Try:

console.log("request: "+JSON.stringify(req));

If you're trying to access flow variables:

var flowVar = apigee.getVariable(req, 'flowVariableName');
