Overview

Error 90174 is a product listing feed error that Amazon returns when a seller provides data in a field that is not compatible with the specified attribute. In plain terms, the system detects that you have entered values into a particular field, but that field cannot actually be used for the attribute you are trying to set. This is a common data validation issue that affects sellers who upload or update product listings through inventory files, flat files, or API feeds.

Key Points / What Sellers Need to Know

• Field-Attribute Mismatch — This error means you placed data in a column or field that Amazon does not recognize as valid for the attribute you are trying to define. The field contains values, but those values cannot map to the intended attribute.
• Feed and Flat File Submissions — Error 90174 most commonly surfaces during bulk uploads via inventory file templates, flat files, or Seller Central feeds. It does not typically appear when editing individual listings through the Seller Central interface.
• Template Version Matters — Outdated flat file templates may include fields that are no longer valid for certain product categories or attribute names, which can trigger this error.
• Category-Specific Attributes — Amazon product attributes vary by category. A field that works in one product category may not be valid in another, leading to this mismatch.

How This Error Occurs

When you submit product data to Amazon through a feed or flat file, the system validates each field against a set of rules for the product category and attribute definitions. Error 90174 is triggered when a field in your submission contains data, but Amazon's catalog system determines that the field is not an accepted input for the attribute you are trying to populate. This can happen if you copied data from one template to another, used an outdated template version, or manually added columns that do not correspond to recognized attributes. The error message specifically names the field and the attribute involved, making it easier to pinpoint the source of the problem.

How to Fix It

The first step is to identify the exact field and attribute named in the error message. Check that you are using the most current version of the flat file or inventory template for your product category by downloading a fresh copy from Seller Central. Compare the column headers in your file against the new template to see if the problematic field exists in the updated version. If the field is not present in the current template, you should remove it from your submission or move your data to the correct field. If you are using the Selling Partner API or a third-party tool to submit feeds, verify that your attribute mappings align with the latest Amazon product type definitions. Amazon periodically updates its catalog schemas, and fields that were previously valid may be deprecated or reassigned.
