The underlying error in #111 is a hard error and turns out to be caused by a merge of the target object https://www.wikidata.org/w/index.php?title=Q3608161&action=history which triggers a wikibase-validator-no-such-entity error from the API.
In case it's needed, the statement was: data-statement-id="7560244" data-property="P1346" data-object="Q3608161"
