Common Errors
Error 18002: Invalid attribute value(s) found: [{"attributeName":"deprecated_variation_theme","reason":"Invalid enumerated value 'OPTICAL_POWER/BASE_CURVE_RADIUS/LENS_ADDITION_POWER/UNIT_COUNT' for attribute 'deprecated_variation_theme'

Error Description

The "Error 18002: Invalid attribute value(s) found" indicates that one or more values provided for the "deprecated_variation_theme" attribute are not valid according to Amazon’s accepted enumerated values. Variation themes are used to group related product variations (e.g., different sizes, colors) under a single parent listing. Amazon periodically deprecates old variation themes and updates the accepted values, and using deprecated or incorrect values leads to this error.

Common Causes:

  1. Deprecated Variation Theme: The variation theme used in the listing has been deprecated and is no longer accepted by Amazon.
  2. Typographical Errors: Mistakes in entering the variation theme values.
  3. Incorrect or Unsupported Values: Using values that are not supported by Amazon for the "deprecated_variation_theme" attribute.
  4. Bulk Upload Issues: Errors in bulk upload files where outdated or incorrect variation themes are specified.

  3. Correct the Variation Theme:

  4. Update Product Listings:
    • Log in to your Amazon Seller Central account and navigate to the problematic product listings.
