Hello,

This error comes from the note type “Sketchy Micro - Pepper / heptachlor,” which is not from an official AnkiHub deck. Also, if images are missing in cards from that deck/note type, the best way to resolve this is to contact the deck owner to clarify the situation. Unfortunately, as this deck is not maintained by the AnkiHub team, I cannot offer that much help.

The only deck you are subscribed to that is an official AnkiHub deck maintained by the AnkiHub team is the AnKing Step Deck. If you’re having issues with cards from that deck, then I will be able to help you if you could give me more details about your issue.
