How to get error information in XmlHttpRequest error event

I have simple code like that:

const request = new XMLHttpRequest();
request.addEventListener('error', logError);
request.open('GET', 'www.someapi.com');
request.withCredentials = true;
request.send();

And logging is like that:

const logError = (error) => {
  console.log(`Error\nEvent:\n${JSON.stringify(error, null, 4)}`);
  // Code to log to server
};

Now what happens is that I get log messages with error, but there is like nothing meaningful in there, just "isTrusted": true. I would like to get more information on what is going on and why I get this error. E.g. in the console I see something like that when I fiddle connection drop:

net::ERR_CONNECTION_RESET

But when it comes to javascript event, it's literally no meaningful information to figure out what is going on. E.g. I have read that CORS can cause it here, but without any message it is very hard to figure out what is going on.

You can check the error log as follow :

const request = new XMLHttpRequest();
request.onerror = function (e) {
                console.log(e);
                reject(new TypeError('Network request failed'));
            };
