Not receiving any data through KiteTicker API

HI Zerodha,

I have installed the NODEJS KiteConnect module and when I execute the following code during MARKET HOURS I am not receiving any tick data. Could someone please help me out:
Code:

var KiteTicker = require("kiteconnect").KiteTicker;
console.log('Successfully imported module');
var ticker = new KiteTicker({
	api_key: "<>",
	access_token: "<>"
});

try {
ticker.connect();
console.log('Called ticker.connect');
ticker.on("ticks", onTicks);
ticker.on("connect", subscribe);

function onTicks(ticks) {
	console.log("Ticks", ticks);
}

function subscribe() {
	var items = [408065];
	ticker.subscribe(items);
	ticker.setMode(ticker.modeFull, items);
}
			} catch (err) {
				console.log(err);
			}

It is neither throwing any error nor giving tick data.

Thanks,
Rajesh
