Overview

Amazon returns error code 8104 when a product feed lacks a title for a specific SKU. The issue appears during bulk uploads, whether through flat files, the SP‑API, or third‑party tools, and it blocks the creation or update of the affected listing. Sellers need to address the missing title promptly to keep new products live and avoid unnecessary delays.

Key Points

• Error trigger — The system flags error 8104 whenever the title column (often “item_name” or “product_name”) is empty for a SKU in the submitted inventory file.
• Affected processes — The error can surface in flat‑file uploads, inventory loader submissions, or any API‑driven bulk feed that transmits product data to Amazon.
• Resolution path — Insert a compliant product title for the identified SKU, save the file, and resend the feed; the listing will be accepted if all other mandatory fields are present.
• SKU identification — Amazon’s response includes the exact SKU that failed validation, allowing sellers to pinpoint the problematic row quickly.
• Impact on feed — Only the rows missing titles are rejected; the remainder of the feed typically processes without interruption.

How Error 8104 Occurs

1. Feed validation stage — When Amazon receives a bulk file, it scans each row for required attributes. For example, a seller uploading a spreadsheet of 500 kitchen gadgets will have the system check every “item_name” entry.
2. Missing title detection — If the title field for SKU “KG‑00123” is blank or the column is omitted, the validator marks that row as non‑compliant and returns error 8104 for that SKU.
3. Partial acceptance — All other rows that contain valid titles continue through the processing pipeline, while the SKU with the empty title remains uncreated or unupdated.

Before / After Comparison

• Before: A seller submits a flat file where the “product_name” column is left empty for several SKUs due to a copy‑paste error. Amazon rejects those rows with error 8104, and the seller must manually locate and edit each missing title.
