Hi,
I'm running into this error when the tests for my changeset ( https://gerrit.wikimedia.org/r/#/c/134064/ ) run on Jenkins:
https://integration.wikimedia.org/ci/job/mwext-MultimediaViewer-qunit/1881/c...
That changeset's parent is the latest master commit, so it's probably not an issue of automerge. The error comes from ResourceLoader when trying to load the dependencies for the tests.
I can't reproduce the error locally, neither on Firefox nor Chrome. It's hard to guess where the error is coming from, as the change is quite large.
Any idea what I could do to resolve the issue? Is there a simple way to reproduce Jenkin's setup locally?
