What it means
Required product attributes vary by item type, destination and the current product data specification.
How to fix it yourself
- Record the exact attribute name shown in the issue details (for example: brand, condition, color, size or google_product_category).
- Check whether the source item actually has that information and whether your feed maps it to the expected attribute name and format.
- For variant products, check that attributes are populated on each relevant variant and that values use supported formats.
- Correct the source data, refresh/resubmit the feed, then verify the issue clears after processing.
