ESP32 WIFI event: post event to user fail!

Task: control the LED on the board using a browser.
Device: ESP32 WROOM DevKit v1, firmware from the espruino_2v04_esp32 folder.
Work in the Espruino Web IDE for Windows 64 bit - 0.72.1.
The code:

var wifi = require('Wifi');
var http = require('http');
var ssid = 'Point';
var password = '12345678';
var port = 80;

function apiRequest(req, res) {
  console.log('apiRequest start');
  var a = url.parse(req.url, true);
  console.log("PATH: ", a.pathname, "METHOD", req.method);
  if (req.method === "POST") {
    switch(a.pathname) {
      case '/setLed':
        var data = "";
        req.on('data', (d)=> { data = d; });
        req.on('end',  ()=> {
          console.log('START Post setLed', data);
          digitalWrite(D2, data === 'true' ? true : false);
          res.writeHead(200);
          res.end();
          console.log('END Post setLed');
        });
        break;
    }
  }
}

function onInit() {
  digitalWrite(D2, false);
  setTimeout(connectWifi, 1000);
  wifi.on('disconnected', ()=> {
    console.log('WIFI disconnected');
  });
  wifi.on('connected', ()=> {
    console.log('WIFI connected');
  }); 
}

function connectWifi() {
  console.log('WIFI connecting...');
  wifi.connect(ssid, {password: password}, (err)=> {
    if(err) console.log(err);
    else {
      http.createServer(apiRequest).listen(port);
      console.log(`Web server running at http://${wifi.getIP().ip}:${port}`);
    } 
  });
}

onInit();

I make a request to the server with the web app and the script works (the LED lights up / goes out)

In console:
