How to Fix Listing Error 90244: Invalid Attribute Values in Your Product Feed
Error 90244 blocks a product feed when an attribute value doesn’t match Amazon’s exact list, such as “blu” instead of “Blue” or a trailing space in “Medium ”. The processing report highlights the offending row (e.g., Row 27 “Color = ‘navy‑blue ’”) so sellers can fix it quickly.
Overview
Error 90244 appears when a product feed contains an attribute value that does not match Amazon’s predefined list for that field. The mismatch stops the feed from being processed, delaying new listings or updates. Sellers who resolve the issue quickly keep their inventory visible and maintain sales momentum.
Key Points
- Restricted‑value attributes — Fields such as Color, Material, Size Type, or Condition accept only the exact terms Amazon publishes; entering “blu” instead of “Blue” triggers the error.
- Hidden characters cause failures — Copy‑pasting from another cell or a web page can introduce non‑printing characters or trailing spaces that look correct but are rejected by Amazon’s validator.
- Processing report pinpoints the culprit — The feed‑processing summary highlights the offending attribute and the exact value that failed, allowing sellers to locate the problem in seconds.
- Drop‑down menus eliminate guesswork — Amazon’s category‑specific templates embed a selectable list for each enumerated attribute; choosing from the list guarantees a valid entry.
- Template version matters — Using an outdated template may present obsolete value sets, leading to error 90244 even when the entered term appears correct for the current catalog.
How to Resolve Error 90244
- Open the processing report — Navigate to the “Processing Summary” tab in Seller Central; the report will list each rejected row and flag the problematic attribute in orange, e.g., Row 27 shows “Color = ‘navy‑blue ’” with an extra space.
- Replace the invalid entry — In the original flat file, click the cell for the flagged attribute and select the correct term from the built‑in drop‑down list (e.g., choose “Navy Blue” directly from the list instead of typing it). This ensures the value matches Amazon’s exact enumeration and removes hidden characters.
- Save and resubmit — After correcting all highlighted cells, save the file in the required format (usually .tab or .xlsx) and upload it again through the “Add Products via Upload” workflow. The new submission should process without generating error 90244.
Analysis & Recommendations
Why This Matters
A rejected feed prevents new listings or updates, causing inventory downtime and lost revenue. Fixing error 90244 within minutes restores visibility, as shown by the before/after example where a trailing space delayed the listing until corrected.
Key Takeaways
- Error 90244 is triggered by mismatched enumerated values like “blu” vs “Blue”.
- Hidden characters (e.g., trailing space in Row 27 “navy‑blue ”) cause the validator to reject the feed.
- Using the template’s built‑in drop‑down list guarantees a valid entry and removes invisible characters.
- Outdated category templates may contain obsolete value sets, still causing error 90244 even with correct terms.
Recommended Actions
- →Open Seller Central > Reports > Feed Processing Summary, locate rows flagged in orange for the invalid attribute.
- →In the flat file, replace each flagged value by selecting the correct term from the drop‑down list in the latest category template.
- →Download the newest template from Seller Central > Inventory > Add Products via Upload before each bulk upload and resubmit the corrected file.
