I get an undefined error first, then I get the proper response (200) right afterward. Any ideas as to why?

// Problem: We need a simple way to look at a user's badge count and JavaScript points
// Solution: Use Node.js to connect to Treehouse's API to get profile information to print out
const profile = require('./profile.js');
const users = process.argv.slice(2)
users.forEach(profile.get);

//Require https module
const https = require("https");
// Require http module for status codes
const http = require("http");

//Print Error Messages
function printError(error) {
  console.error(error.message);
}

// Function to print message to console.
function printMessage(username, badgeCount, point) {
  const message = `${username} has ${badgeCount} total badge(s) and ${point} points in JavaScript`;
  console.log(message);
}


function get(username) {
  try {
    // Connect to the API URL (https://teamtreehouse.com/username.json)
    const request = https.get(`https://teamtreehouse.com/${username}.json`, (response) => {
      if (response.statusCode === 200 ) {
        let body = "";
        // Read the data
        response.on('data', data => {
          body += data.toString();
        });

        response.on('end', () => {
          try {
            // Parse the data
            const profile = JSON.parse(body);
            // Print the data
            printMessage(username, profile.badges.length, profile.points.JavaScript);  
          } 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);
      }
    }).on('error', printError(error))
  } catch (error) {
   printError(error);
  }
}

module.exports.get = get;
