All builds since #40 have failed for the same reason.
The key part of the report is:
Edit failed: Error: Error returned by API: Wikipedia has restricted the ability to create new pages. You can go back and edit an existing page, or [[Special:UserLogin|log in or create an account]].
It is not possible to create a new page as an anonymous user on the Beta Cluster which is the reason for the problem.
Suggested Fixes
As I commented in T176315#3626845, it looks like the failing test doesn't log in before trying to create/edit the Related Articles 1 page.
Use @zeljkofilipin's snippet from T162256#3588456 to login on line 12 of tests/selenium/specs/readmore.js.
