Overview

Sellers uploading bulk inventory files to Amazon sometimes encounter error code 8002, which blocks the affected listings from processing. The issue appears when a field that must contain the literal value “1” receives any other entry, or when the feed includes a column that Amazon’s current system does not recognize. Fixing the problem quickly restores the feed’s flow and prevents sales delays.

Key Points

• Trigger condition — The error fires if a required flag column (e.g., IsActive) contains “0”, “true”, or any whitespace instead of the exact digit 1.
• Unsupported column — Including a legacy field such as LegacyProductType that Amazon has retired also generates error 8002, regardless of the value supplied.
• Simple remedy — Correct the offending value to “1” or delete the unsupported column; no additional code changes are needed.
• Validation importance — Running the file through a pre‑upload validator catches the mistake before Amazon processes the feed, saving hours of re‑work.
• Tool impact — Third‑party listing software that still references old templates often injects the invalid column automatically, so sellers must update those integrations.
• Revenue risk — Each hour a bulk upload stalls can cost sellers dozens of sales, especially in fast‑moving categories where inventory turnover is high.

How Error 8002 Happens

1. Field value mismatch — During the feed generation, a Boolean‑style flag (for example, IsDiscontinued) is set to “0” to indicate the product is active. Amazon expects only “1” for this flag, so the upload returns error 8002 for every row containing the wrong value.
2. Legacy column inclusion — A seller copies an old flat‑file template that still lists ProductGroupID. Because Amazon no longer supports this column, the system flags every row that contains it, producing the same error code.
3. Automated tool injection — A third‑party inventory manager populates a custom attribute with the text “N/A”. The attribute is not mapped in Amazon’s current schema, so the feed is rejected with error 8002 for each affected SKU.
