Current suspect is the code change related to T236691: Implement alternative `SiteLinkLookup` for MediaInfo entities
Comment Actions
It was indeed an issue with https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/Wikibase/+/550494/ and an array_merge there.
This merge tries to the use behaviour described below:
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
however the things being merged have int keys, and the result just ends up broken.
