Overview

Error 13002 is a feed processing error that Amazon returns when a seller submits an inventory feed containing an invalid value in a field that requires a boolean (true/false) input. This is one of the more common feed validation errors encountered by sellers who manage their catalog through flat file uploads or API-based inventory feeds.

Key Points / What Sellers Need to Know

• Error trigger — This error fires when Amazon's feed processor encounters a value that isn't recognized as a valid boolean in a field that expects one. Common culprits include typos, numeric entries like "1" or "0," or leaving the field blank when a value is required.
• Valid values only — The only accepted values for boolean fields in Amazon inventory feeds are true and false (lowercase). Variations such as "yes," "no," "TRUE," or "1" will be rejected.
• Feed-level impact — The error applies to individual rows within your inventory feed. Other rows with correct values will typically still process, but the affected rows will fail until corrected.
• Quick resolution — Fixing this error requires resubmitting a corrected inventory feed with proper boolean values in the flagged field.

What Causes Error 13002

This error occurs during inventory feed processing when Amazon's system validates the data you've submitted and finds a value that doesn't conform to the expected boolean format. Boolean fields in Amazon's feed templates are used for a variety of product attributes — things like whether an item is discontinued, whether gift wrapping is available, or whether a product is marked as an adult item. When sellers populate these fields using spreadsheet software, it's easy to introduce formatting issues. Excel, for example, may auto-capitalize entries to "TRUE" or "FALSE," or auto-correct values in unexpected ways. Copy-pasting from other systems can also introduce hidden characters or whitespace that cause validation failures.

How to Fix It

To resolve Error 13002, download your most recent inventory feed file and locate the row or rows that triggered the error. Identify which field contains the invalid value — Amazon's feed processing report will typically indicate the specific SKU and field involved. Replace the invalid entry with either or in lowercase, ensuring there are no extra spaces, quotation marks, or hidden characters surrounding the value. Once corrected, resubmit the modified inventory feed through Seller Central's upload interface or via the Feeds API. After submission, check your feed processing report to confirm the error has been resolved and the affected listings have been updated successfully.
