I did some investigation with the help of @Lucas_Werkmeister_WMDE and @Ladsgroup but didn't find the root cause so far. As far as we can tell, the content is **exactly** the same. We have seen such a phenomenon before when the serialization of entities changed, but this would have to have (also) happened between 20th of March and 18th of April <https://www.wikidata.org/w/index.php?diff=917938818&oldid=889025858&title=Q1471595&curid=1409628>. And so far I didn't find any candidate for that. - The content seems to be exactly the same, even of those revisions whose size apparently changed: API query with prop=revisions <https://w.wiki/3KH> - There are some null-edits where content size increased and some null-edits where it stays the same. So far I didn't find any null-edits where it decreased. - we got the API query that made the null-edit from hadoop. It contains an empty `data` object: `{}`: wikidatawiki 323 false [] {"summary":"nl-description, [[User:Edoderoobot/Set-nl-description|python code]], logfile on https://goo .gl/BezTim","maxlag":"15","data":"{}","assert":"user","bot":"1","format":"json","action":"wbeditentity","id":"Q1471595","baserevid":"889025858","token":"[redacted]"} 2019 4 18 14 - Even with this exact query <https://wikidata.beta.wmflabs.org/wiki/Special:ApiSandbox#action=wbeditentity&format=json&maxlag=15&assert=user&id=Q9&baserevid=775459&bot=1&data={}> I cannot reproduce this issue. - The bot is still running <https://www.wikidata.org/wiki/Special:Contributions/Edoderoobot> and the problem persists <https://www.wikidata.org/w/index.php?diff=924246324&oldid=169164101&title=Q2313457> TASK DETAIL https://phabricator.wikimedia.org/T220904 WORKBOARD https://phabricator.wikimedia.org/project/board/3539/ EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: Michael Cc: Michael, Ladsgroup, Lucas_Werkmeister_WMDE, matej_suchanek, Lydia_Pintscher, Edoderoo, Bencemac, Aklapper, alaa_wmde, Nandana, Lahi, Gq86, GoranSMilovanovic, QZanden, LawExplorer, _jensen, rosalieper, Jonas, Wikidata-bugs, aude, Mbch331
