Problem is the response in res.send is undefined.

app.get('/products', function(req, res) {
  var Client = http.createClient(80, 'local.10layer.com');
  var request = Client.request("GET", '/workers/api/section/products', {'host' : 'local.10layer.com'});
  
  request.addListener("response", function(response) {
    var body = "";                                                                                                                                                                                                                                                              
    response.addListener("data", function(data) { //Add listener for the actual data
      body += data; //Append all data coming from api to the body variable
    }); 

    response.addListener("end", function() { //When the response ends, do what you will with the data
      var response = JSON.parse(body); //In this example, I am parsing a JSON response
      console.log(response);
    }); 
  }); 

  request.end();
  res.send(response);
