Vector relies on raw assets to build documentation as part of one of its CI steps. Previously it was using github but migrated to Phabricator after being told that we should dog food our own tools.
This historically has come from a URI in Phabricator such as "https://phabricator.wikimedia.org/source/mediawiki/browse/master/resources/src/mediawiki.less/mediawiki.mixins.less?view=raw"
This no longer works for some reason, redirecting to
https://phabricator.wikimedia.org/file/view/31771082/source/
This means all Vector patches are blocked by CI for now.
Short term fix: disable the job
Longer term fix: Please provide a stable URI for accessing raw assets from repos.
(I'll be back to this on Monday!)
