Overview

Error 90229 is a product listing validation error that Amazon sellers encounter when submitting or updating product listings through Seller Central, flat files, or API integrations. The error indicates that at least one required attribute from a specific group of fields has not been provided. Understanding this error and how to resolve it is essential for sellers who need to get their products listed quickly and avoid delays in their catalog management workflow.

Key Points / What Sellers Need to Know

• What the error means — Error 90229 triggers when Amazon's listing system detects that none of the attributes from a required attribute group have been filled in. The error message reads: "At least one of '{attribute_names}' is required," where the placeholder shows which specific fields need attention.
• It applies to attribute groups, not single fields — Unlike errors that flag a single missing field, Error 90229 refers to a group of related attributes where at least one must be provided. Sellers have flexibility in choosing which attribute from the group to supply.
• Common trigger points — This error frequently appears during bulk uploads via flat files, API-based listing submissions, and manual listing creation when certain conditional fields are left entirely blank.
• Category-specific requirements — The specific attributes referenced in the error vary by product category. What triggers this error in clothing may differ entirely from electronics or grocery items.

How This Error Works

Amazon organizes product listing attributes into groups where certain combinations are conditionally required. Rather than mandating every single field, Amazon requires that sellers provide at least one attribute from a defined set. For example, a product category might require at least one identifier such as a UPC, EAN, or GTIN. If a seller submits a listing without any of these identifiers, Error 90229 will fire and the listing submission will be rejected. The specific attribute names referenced in the error message will tell sellers exactly which group of fields needs attention, making diagnosis relatively straightforward once sellers know where to look.
