Error 8022 — Invalid relationship type

The relationship_type attribute has an invalid value. Amazon expects 'Variation' for parent-child relationships, with specific allowed alternatives.

Typos in relationship_type, or use of deprecated values like 'Accessory' that Amazon retired.

1. Set relationship_type='Variation' for all variant child rows.
2. Parent rows leave relationship_type blank.
3. Other valid types are category-specific — check the category guide before using.

• Using 'variation' (lowercase) when 'Variation' is required
