Overview

Error 99019 is a feed processing error that Amazon sellers encounter when submitting product listings with missing or invalid attribute values. This error fires when Amazon's system expects at least one of two interdependent fields to contain valid data, but both are left blank or improperly formatted. Understanding how to diagnose and resolve this error can save sellers significant time during catalog uploads and listing updates.

Key Points / What Sellers Need to Know

• Interdependent attributes — Amazon pairs certain listing fields together and requires sellers to provide a valid value in at least one of them. If both are left empty, the feed will be rejected with error 99019.
• Common trigger — This error most frequently appears during bulk uploads via flat files or API-based feed submissions where required field combinations are overlooked.
• Feed processing summary — The specific attribute names causing the error are identified in your feed processing summary report, replacing the placeholder variables shown in the error message template.
• Format matters — Even if you populate one of the required fields, the value must conform to Amazon's expected format and validation rules for that particular attribute.

How This Error Works

When Amazon processes a product feed, it validates each listing against a set of attribute rules. Some attributes are grouped in pairs where the system requires at least one to be present. For example, Amazon may require either a UPC or an EAN for product identification, or either a brand name or a manufacturer name for certain categories. When the system detects that both fields in a required pair are empty or contain values that fail validation, it triggers error 99019 and rejects that specific listing from the feed. The error message itself will identify the two fields involved, displayed in place of the generic placeholders.

How to Resolve Error 99019

The first step is to download and review your feed processing summary report from Seller Central. Navigate to the inventory section and locate the feed submission that generated the error. The report will clearly identify which two attribute fields triggered the rejection, replacing the template variables with actual field names relevant to your product category. Once you know which fields are involved, populate at least one of them with a valid value. Double-check that the data you enter matches the format Amazon expects — for instance, numeric fields should not contain text, date fields should follow the required date format, and enumerated fields should use one of Amazon's accepted values. After making corrections, resubmit your feed and monitor the processing report to confirm the error has been cleared.
