Error message
Bad Request: validation errors found
What does this error mean?
The Zalando API rejected the data because specific product attributes, likely related to material composition, did not meet mandatory validation requirements.
How to solve it
Identify the affected attributes: Check your integration report for other errors on this product to pinpoint the exact missing or invalid fields (typically "material.filling.material" or "material.futter_clothing").
Fill the missing attributes or create a Lengow Rule: Update these fields directly in your Attributes Mapping. If the data is missing from your source, you can create a rule to automatically fill empty fields with accepted default values (like "not_applicable" or "100"). See our dedicated guide about Zalando Material for more details.
Resynchronize your feed: Once updated, perform a manual full push to send the corrected data to Zalando.
