Error message
"quantity_de": the value must be greater than or equal to 0
What does this error mean?
This error occurs because the stock value provided for the attribute quantity_de is negative (less than 0). Zalando does not accept negative stock levels and requires all product quantities to be either 0 or a positive number.
How to solve this error
- Check your stock values: Go to your attributes mapping and verify the field mapped to quantity_de to identify which products are sending negative quantities.
- Adjust the values: Correct the negative stock values directly in your source catalogue, or create a rule to automatically replace any negative value with 0.
- Do a push: Once you have adjusted your mapping or saved your rule, do a push to apply your changes and send the updated product data to Zalando.
