Protractor - unable to get URL title, webdriver just hangs - automation

Question

just start messing around with Protractor for an upcoming project that may require front-end automation on an angular based website. After installing Protractor and running the given examples, tried to do a very simple test, like the following:
// test.js
describe('Protractor Demo App', function() {
it('should have a title', function() {
browser.get('http://www.google.co.uk');
expect(browser.getTitle()).toEqual('Google');
});
});
Problem is, the browser opens but then it just hangs until it closes with an error:
Failures:
1) Protractor Demo App should have a title
Message:
Failed: Cannot read property 'ver' of null
Stack:
TypeError: Cannot read property 'ver' of null

have no idea why this simple test does not work. Any help is welcome, thanks in advance

It would be a great decision to disable Control Flow due to this thread . In your protractor.conf.js file add SELENIUM_PROMISE_MANAGER: false line. After it you should resolve Promises by yourself. For example your test will look like:
describe('Protractor Demo App', function() {
it('should have a title', async function() {
await browser.get('http://www.google.co.uk');
expect(await browser.getTitle()).toEqual('Google');
});
});
