Pinterest needs a working image URL for every product. Error 111 fires when the image_link field is missing entirely; the row is dropped from ingestion.
Pinterest is image-first, so image_link is non-negotiable. Most often this is a feed mapping mistake - the source platform stores images in a 'photo' or 'media' column that was not mapped to image_link. For variant-level feeds, only the parent SKU sometimes has an image while children inherit nothing.
