Error 254: page loading failed in PhantomJS

[gmetais]

The Error 254 happens on some website when PhantomJS is not able to open the page, for one of the following reasons:

• the url is incorrect
• the url is redirected with JavaScript to another url
• the server's SSL certificate has a problem
• other reasons we need to understand...

If you encounter this bug and would like to help finding the cause, please add a comment with the following template:

I'm rewriting here an error from #140.

Webpage URL: https://www.americanfunds.com/advisor/
Tested device: desktop
Redirection: yes, a double redirection on this page when the user doesn't have any cookie
SSL certificate (if https): correct and not expired
Number of seconds before it crashes: approx. 30
Other information that could help debugging: ``

My note about the reported bug:

It seems that the test is failing because of a double redirection on this page when the user doesn't have any cookie.

First redirection : https://www.americanfunds.com/advisor/ --> https://www.americanfunds.com/advisor/public/authentication-0.htm?next=/advisor/

Second redirection : https://www.americanfunds.com/advisor/public/authentication-0.htm?next=/advisor/ --> https://www.americanfunds.com/advisor/

Phantomas doesn't like JavaScript redirections. If you can add the right cookie in the options, than it should work.

Same issue with news.bbc.co.uk

Thank you for reporting the error. I don't have a solution for you, I'm juste writing here what I found.

This is again an issue with redirections, which are badly handled by Phantomas.
On this WebPageTest waterfall we can see: http://www.webpagetest.org/result/161027_A0_2532e2a01759f3710b53142a070061f6/1/details/#waterfall_view_step1

When entering the last URL in YLT, the output is not an error 254 but 255, which is a progress. This error seem to occur when the page is too complex, with a lot of DOM access. PhantomJS runs out of memory and crashes with error 255. It works when I run YLT on my computer, which has more memory.

It looks like there is a massive use of $(window).height() and $(window).scrollTop() during page load and that could break YLT. It's probably a script that handles the lazyloading of images.

Do you work for the BBC? Can you confirm this?

Hi

Any plans to fix this? I have this with latest patch 1.13.4
