While a store has no explicit recipient, the list contains a fallback entry (
isPrimary: true, the owner’s account email) whose id is a sentinel of the form OWNER_<storeId>. Sending that id here materializes it: the account email becomes a real recipient, your patch is applied on top of the store-level notify* toggles, and the response carries a real UUID. The fallback entry then disappears.Request Body
