Amazon error message (example)
item_weight.0: 'unit' is a required property
What this error means
Amazon received a weight value (e.g., “500”) but the unit of measurement (g, kg, lb, oz) was missing. Both the value and the unit are required for Amazon to process this attribute correctly.
How to fix the error
Ensure your feed includes both:
- item_weight..value: the numeric weight of the product, and
- item_weight..unit: the unit of measure (e.g., g, kg, lb, oz)
Double-check that the unit used is accepted for your product category.
