Keep getting the error response regardless of profile name?

I realized that the error div is being returned for every user name I typed in. I am sometimes getting an error message in the console regarding events.js line 85. Not sure what is going on here?

Hi Anthony,

Can you snapshot your workspace for us? It's the arrow icon next to the eye icon in the workspace window. That way we can see what's going on.

profile.js

var EventEmitter = require("events").EventEmitter;
var http = require("https"); 
var util = require("util");
// ...code ommited...
// line 23
            profileEmitter.emit("error", new Error("There was an error getting the profile for " + username + ". (" + http.STATUS_CODES[response.statusCode] + ")"));

STATUS_CODES is one of the few things node's https doesn't replicate from http, and using https in it's place here is causing the error. (Check the stack trace, it should mention profile.js at or near the top)

So...

If I change var http = require() from http to https, I still keep getting the same error.

What is the solution here?

Having the same issue, i solved it using both https for the API call and http for getting the status code: 

............
var https = require("https");
var http = require("http");
..........
var request = https.get("https://teamtreehouse.com/" + username + ".json", function(response) {

        var body = "";

        if (response.statusCode !== 200) {

            request.abort();
            //Status Code Error
            profileEmitter.emit("error", new Error("There was an error getting the profile for " + username + ". (" + http.STATUS_CODES[response.statusCode] + ")"));
        }
...........

I don't know if this is a good practice but solved the issue.....
