Unable to Connect to Xirsys STUN and TURN servers using EasyRTC - webrtc

Question

I'm working on a video chat application using EasyRTC and Xirsys. It works fine on its own (using the Google STUN server), but fails when I create a listener for the getIceConfig event. The EasyRTC server is on port 8080, and I also have an Apache server running on port 80. I've set up my server.js file as follows:
// Load required modules
var http = require("http"); // http server core module
var express = require("express"); // web framework external module
var io = require("socket.io"); // web socket external module
var easyrtc = require("../"); // EasyRTC external module
// Setup and configure Express http server. Expect a subfolder called "static" to be the web root.
var httpApp = express();
httpApp.use(express.static(__dirname + "/static/"));
// Start Express http server on port 8080
var webServer = http.createServer(httpApp).listen(8080);
// Start Socket.io so it attaches itself to Express server
var socketServer = io.listen(webServer, {"log level":1});
easyrtc.setOption("logLevel", "debug");
// Overriding the default easyrtcAuth listener, only so we can directly access its callback
easyrtc.events.on("easyrtcAuth", function(socket, easyrtcid, msg, socketCallback, callback) {
easyrtc.events.defaultListeners.easyrtcAuth(socket, easyrtcid, msg, socketCallback, function(err, connectionObj){
if (err || !msg.msgData || !msg.msgData.credential || !connectionObj) {
callback(err, connectionObj);
return;
}
connectionObj.setField("credential", msg.msgData.credential, {"isShared":false});
console.log("["+easyrtcid+"] Credential saved!", connectionObj.getFieldValueSync("credential"));
callback(err, connectionObj);
});
});
// To test, lets print the credential to the console for every room join!
easyrtc.events.on("roomJoin", function(connectionObj, roomName, roomParameter, callback) {
console.log("["+connectionObj.getEasyrtcid()+"] Credential retrieved!", connectionObj.getFieldValueSync("credential"));
easyrtc.events.defaultListeners.roomJoin(connectionObj, roomName, roomParameter, callback);
});
// Start EasyRTC server
var rtc = easyrtc.listen(httpApp, socketServer, null, function(err, rtcRef) {
console.log("Initiated");
rtcRef.events.on("roomCreate", function(appObj, creatorConnectionObj, roomName, roomOptions, callback) {
console.log("roomCreate fired! Trying to create: " + roomName);
appObj.events.defaultListeners.roomCreate(appObj, creatorConnectionObj, roomName, roomOptions, callback);
});
});
easyrtc.on("getIceConfig", function(connectionObj, callback) {
// This object will take in an array of XirSys STUN and TURN servers
var iceConfig = [];
request({
url: 'https://service.xirsys.com/ice',
qs: {
ident: "***",
secret: "***",
domain: "***",
application: "default",
room: "default",
secure: 1
},
function (error, response, body) {
if (!error && response.statusCode == 200) {
// body.d.iceServers is where the array of ICE servers lives
iceConfig = body.d.iceServers;
console.log(iceConfig);
callback(null, iceConfig);
}
}
});
});

Any ideas about what is causing this? It happens in both chrome and firefox. Thanks.

Here's your error:
ReferenceError: request is not defined
You forgot to invoke request with the http object.
Here's your fix:
Change this:
request({
url: 'https://service.xirsys.com/ice',
...
To be this:
http.request({
url: 'https://service.xirsys.com/ice',
...
