undefined body variable

Here is my code.

var username = 'philiprurka';
var https = require('https');

function printMessage(username, badges, points) {
   var message = username + ' has ' + badges + ' total badges and ' + points + 'points in JavaScript.';
   console.log(message);
};

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

   response.setEncoding('utf8');

   response.on('data', function(chunk){
      body += chunk;
   });

   response.on('end', function(body){
      console.log('BODY: ' + body);
   });
});


request.on("error", function(error) {
   console.error(error.message);
});

The json link works fine. I have tested it. The problem is that when I run this with node.js, It returns with 'BODY: undefined'. I can't figure out why.

response.on('end', function(body){
      console.log('BODY: ' + body);
   });

remove the 'body' argument from the function. You have already declared it
