eBay Error 21916714: Either a Variation or Pictures container must be supplied if the request has a Variations container.

Why this happens

The listing is marked as a variation listing but no actual variations (or variation pictures) were sent, usually because all variations were removed or are empty. Why eBay enforces this: A listing marked as a variation listing must contain variations. Sending the structure without any variation data leaves eBay with nothing to publish. When it usually happens: It usually appears after deleting all variations while keeping the product in variation mode.
