Troubleshooting is type in every aspect of computer systems and development — this article begins with simple tips to figure this nagging issue out all on your own. In the event that you don’t care, jump into the TL;DR by the end.
If you’re having problems with headless mode, make wix contact sure to have a screenshot with page.screenshot() and that means you can see what’s happening. At the very least it shows you if you’re coping with exactly the same noticeable content you have got with headed mode and you’re perhaps not stuck at a broken script without understanding exactly what you’re using the services of.

Which means that a host someplace produced call based strictly on which we delivered for the very first request and our block has nothing at all to do with page content. That guidelines out troubleshooting any such thing following the web page render and limits our range towards the demand alone. The demand itself is a lot of bits and bytes delivered online and accepted by way of a host.

This points us towards the content regarding the demand alone. We are able to make use of a ongoing solution that echos back our HTTP needs to examine the distinctions between a demand produced from headless and headed Chrome. The after script utilizes http://scooterlabs.com/echo.json to have a JSON response that represents the demand the server received.
By operating this both in headless (the standard) and mode that is headedby changing the launch properties to incorporate headless:false ) we can diff the output to see just what, if any, distinctions you can find.
