lazyimages_without_scroll_events.js finishes with error TimeoutError: Navigation Timeout Exceeded

I try to check lazy loading for site using Google official guide.

I've inited project from git, installed all dependencies.

When I run

node lazyimages_without_scroll_events.js -h --url==https://dns-shop.ru

I get an error below:

(node:7280) UnhandledPromiseRejectionWarning: TimeoutError: Navigation Timeout Exceeded: 30000ms exceeded

(node:7280) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

And process hangs forever.

Node version is v10.15.3, platform is Windows 7.

What are steps to check the site correctly?

What happens if you remove the -h flag?
