- See mk:Категорија:Леднички земјишни облици and the correctly displayed language links there (and the corresponding Wikidata item).
- Compare with an API example reporting the page has no language links. (And the same shows in the langlinks database replica on Toolforge.)
I have received an error report about my Toolforge tool not working for some recently created categories on mkwiki.
The problem seems to be that some pages on mkwiki are missing entries in the langlinks table, even though the page is linked with a Wikidata item with many sitelinks, and the Wikipedia category page even displays those links correctly.
However, there are no langlink rows for the page in the Toolforge database replica, and the mkwiki API returns no langlinks for the page as well: See an API example contrasting the missing langlinks with another recently created category, which lists them correctly.
I guess this probably comes from some issue when syncing/updating changes in Wikidata to the local wiki database. It might be the same or similar issue as reported in T297238? (In that case, feel free to mark this a duplicate.) However, even though I understand distributed systems will necessarily experience similar issues, I am not sure if there is any remedy available: Would any edit to the respective Wikidata item help force the refresh? Or removing and re-adding the corresponding mkwiki sitelink from Wikidata? Purging some of the pages? Something else?
