[Wikidata-bugs] [Maniphest] [Edited] T168876: MWAPI service throws “could not find binding for parameter” if optimizer is not disabled

CHANGES TO TASK DESCRIPTION

...

If the optimizer is disabled via query hint, the query works (though it finds no results, but that’s another topic: T168877), so it looks like the optimizer reorders the query in such a way that the service doesn’t have access to the `?file` binding.
