To clarify, this is with wmf.26, not wmf.27, right? Because then I think it’s a dupe of T189842: Undefined index error in CachingResultsBuilder when checking constraints on empty entity. (In .27, CachingResultsBuilder has been replaced by CachingResultsSource.)
@Lucas_Werkmeister_WMDE indeed wmf.26 not 27. I apologize for the dupe, My search didn't match T189842
Phew, you scared me with this happening right around the train :D thanks for confirming, in that case this should be fixed in a few hours.
