not getting the right http status code to display

My code runs fine but I have an issue for the display of my status code. It is showing found when I input an invalid user, but showing the correct error message.

const https = require('https');
const http = require('http');

// Print the data
function printMessage(username, badgeCount, points, totalPoints) {
    const message = `${username} has ${badgeCount} total badge(s) and ${points} points in JavaScript, and ${totalPoints} total points`;
    console.log(message);
}

function printError(error) {
    console.error(error.message);
}

function getProfile(username) {
    // connect to the API URL (https://teamtreehouse.com/profiles/csalgado.json)

    try{
    const request = https.get(
        `https://teamtreehouse.com/profiles/${username}.json`,
        (response) => {
            if(response.statusCode === 200){
            let body = "";
            console.log(`statusCode : ( ${response.statusCode} )`); 

             // Read the data
            response.on("data", (data) => {

                // console.dir(data); 
                //------- this shows buffers

                body += data.toString();
            });

            response.on("end", () => {     

 // Parse the data

                try {
                let profile = JSON.parse(body);

                printMessage(username, 
                    profile.badges.length, 
                    profile.points.JavaScript, 
                    profile.points.total
                );
            }
                catch (error) {
                    printError(error); 
                }
            });
        }
            else {
                const message = `There was an error getting the profile for ${username} (${http.STATUS_CODES[response.statusCode]})`;
                const statusCodeError = new Error(message);
                printError(statusCodeError);
            }
        }
    );
    request.on('error', (error) => printError(error));
    } catch(error) {
        printError(error);
    }
}


const users = process.argv.slice(2);
users.forEach(getProfile);

The Treehouse server doesn't send a 400 error code when a profile isn't found. Instead, it sends a 302 ("found", but with redirect) with a location update that would divert a browser to the home page.
