Courses Plus Student 4,871 PointsThere was an error getting the profile for hellochalkers (Found) statusCode is 302 for invalid profiles & 404 for valid
Can't find the reason why statusCode for valid profiles is 404 and invalid profiles is 302. Please look at the files below.
//File: profile.js
var EventEmitter = require("events").EventEmitter; var https = require("https"); var http = require("http"); var util = require("util");
/**
- An EventEmitter to get a Treehouse students profile.
- @param username
- @constructor */
function Profile(username) { EventEmitter.call(this); profileEmitter = this; //Connect to the API URL (https://teamtreehouse.com/username.json)
var request = https.get(`https://teamtreehouse.com/profiles/${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] + ")"));
}
//Read the data
response.on('data', function (chunk) {
body += chunk;
profileEmitter.emit("data", chunk);
});
response.on('end', function () {
if(response.statusCode === 200) {
try {
//Parse the data
var profile = JSON.parse(body);
profileEmitter.emit("end", profile);
} catch (error) {
profileEmitter.emit("error", error);
}
}
}).on("error", function(error){
profileEmitter.emit("error", error);
});
});
}
util.inherits( Profile, EventEmitter ); module.exports = Profile;
//File: renderer.js
var fs = require("fs");
function mergeValues (values, content){ //Cycle over the keys for (var key in values){ //Replace all the {{keys}} with the value from the values object content = content.replace("{{" + key + "}}", values[key]); } //Return merged content return content; };

230,688 PointsFrom answering a previous question, I'm aware that the server now sends a redirect (302) to an information page when you attempt to access an invalid profile name. So that behavior is correct. You might want to contact Support to suggest they add something to the Teacher's Notes to explain the new system.
