2 days ago I have started to receive unexpected alerts when leaving the page (actions that change the URL really). (those alerts do not appear in a 'real' browser).

I have checked the compatibility between Chrome and Chromedriver, but the versions are compatible)

Here is the error trace. (You can see the versions of Chrome and Chromedriver)

Failed: unexpected alert open: {Alert text : }
    (Session info: chrome=71.0.3578.98)
    (Driver info: chromedriver=2.45.615291 (ec3682e3c9061c10f26ea9e5cdcf3c53f3f74387),platform=Windows NT 10.0.17134 x86_64)

Is anyone else having this problem?

I have tried the following (without any success), as the alerts can be displayed triggered by many actions, but it did not work.

 capabilities: {             //conf.js
        'browserName': 'chrome',
        'unexpectedAlertBehaviour': 'ignore'

Using 'accept' or 'dismiss' do not work either.

I am running out of ideas, so any advice is welcome.

  • Do you have a minimal test example and a website that makes the issue occur?

Yep, found few solutions: here

What worked for me is:

browser.get(url).catch(function () {

  return browser.switchTo().alert().then(function (alert) {

      return browser.get(url);


  • Thanks @Michal Dobrzycki! I also use this solution and the result was the same, The issue seems to be something around communication in our own system.

You should also try "--disable-notifications" for chromeOptions
