Error 8001 — Required attribute missing or invalid

A required attribute for the product type is missing or contains a value Amazon can't validate. Listing rejected.

1. Check the processing report for the specific attribute name.
2. Look up the category's required attributes in Category Listings Reports.
3. Populate with valid values matching the expected format.
4. Resubmit.

• Submitting numeric values where Amazon expects 'value + unit' (e.g., '5 cm' not '5')
