Reported on https://www.wikidata.org/wiki/Wikidata:Contact_the_development_team#Strange_error_message When trying to edit the claim value for a calim that has had a reference added through wbsetreference we get the error message "Failed to get claim from claim Serialization If a hash is present in a reference serialization it needs to be correct" It appears something is wrong with the hash which makes it uneditable?
As far as I can tell / guess this is caused by the change in the date in the reference which can be seen at http://www.diffchecker.com/b04b7pee The date changing from "time":"+00000002013-10-18T17:21:07Z", to "time":"+00000002013-10-18T00:00:00Z", seems to make the claim editable again? per testing on https://www.wikidata.org/wiki/Q15078282
So, to update the bug it looks like around 40,000 claims are affected by this per the conversation on Contact the Dev Team. This will be the claims for P141 created by SuccuBot https://www.wikidata.org/wiki/Special:WhatLinksHere/Property:P141 These can be fixed by simply passing in a new date. Of course there is still something in the code of wbsetreferece / the validators parsers etc that needs to be fixed to stop this happening in the future..
Can reproduce on master with https://www.wikidata.org/wiki/Special:ApiSandbox#action=wbsetreference&format=json&statement=Q4115189$ff893c9e-4c9b-d34e-fb74-f40a8e5e38ea&snaks={ "P248":[ { "snaktype":"value", "property":"P248", "datavalue":{ "value":{ "entity-type":"item", "numeric-id":15043677 }, "type":"wikibase-entityid" } } ], "P627":[ { "snaktype":"value", "property":"P627", "datavalue":{ "value":"106003204", "type":"string" } } ], "P813":[ { "snaktype":"value", "property":"P813", "datavalue":{ "value":{ "time":"+00000002013-10-05T15:24:21Z", "timezone":0, "before":0, "after":0, "precision":11, "calendarmodel":"http://www.wikidata.org/entity/Q1985727" }, "type":"time" } } ] }&summary=test&token=TOKEN
