I am getting "Missing field sku" and "No global identifier provided (e.g., gtin, mpn, isbn)" warnings from Google Search Console only when products are Out of Stock. I have the following code from FeedArmy in my product-template.liquid. Can anyone tell me how to edit this code to populate the SKU and GTIN for products that are out of stock? I realize these are "just warnings" from Google and not errors, but I'd like to resolve them. Thanks in advance for any help.
