Error message appears on deck completion--but only for some decks

Whenever I finish a deck, before the “Congratulations on finishing this deck” page shows, I get the following error message (see below). I already checked my addons and disabled them and none of them seemed to be the issue. Nothing seems to be wrong with my anki function and syncing other than receiving the “ERROR” message when completing a deck.

Hi, yeah I’ve tried everything except updating to the newer anki and keeping it. I don’t like the new format of the home page on the versions of anki that are 2.1.45 and after (I updated and then downgraded bc I disliked it so much); it added an extra column and switched the due/new columns
