Node.js client app crashes during http request

I'm new to node.js; I am reading a book and following it word for word. I have recently run into a problem and I do not know how to solve it. The book asks me to create a client app, I have the code which matches the book's exactly but doesn't run. Below is the code:

fiboclient.js:

var http = require('http');
var util = require('util');
[
    "/fibonacci/30", "/fibonacci/20", "/fibonacci/10",
    "/fibonacci/9", "/fibonacci/8", "/fibonacci/7",
    "/fibonacci/6", "/fibonacci/5", "/fibonacci/4",
    "/fibonacci/3", "/fibonacci/2", "/fibonacci/1"
].forEach(path => {
        util.log('requesting ' + path);
        var req = http.request({
                host: "localhost",
                port: 3002,
                path: path,
                method: 'GET'
         }, res => {
                 res.on('data', chunk => {
                         util.log('BODY: ' + chunk);
                 });
         });
         req.end();
});

package.json:

{
  "name": "fibonacci",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "DEBUG=fibonacci:* node ./bin/www",
    "server": "SERVERPORT=3002 node ./fiboserver",
    "client": "node ./fiboclient"
   },
   "dependencies": {
     "body-parser": "~1.17.1",
     "cookie-parser": "~1.4.3",
     "debug": "~2.6.3",
     "ejs": "~2.5.6",
     "express": "~4.15.2",
     "morgan": "~1.8.1",
     "serve-favicon": "~2.4.2"
   }
}

output:
