Overview Errors and Warnings

  1. Below is a list of common validation errors and warning with solutions from Amazon Australia.
  2. These listing errors and warnings do change and are updated from time to time, we are always adding new errors as they appear.
  3. If you have a product validation error for warning that is not on this list please let us know.

message=The attributes are invalid., severity=ERROR, attributeNames=[recommended_browse_nodes]

Error message

message=The attributes are invalid., severity=ERROR, attributeNames=[recommended_browse_nodes]

What it means

Amazon does not accept the recommended_browse_nodes attribute for the product type being submitted.

An Omnivore category usually has one product type, but it can have more than one. The attribute may not be valid for the specific product type Amazon is using.

Common causes

  • The attribute is not valid for the Amazon product type
  • The Omnivore category/product type mapping may be stale
  • Amazon’s category requirements may have changed
  • Omnivore and Amazon may disagree on whether the attribute is available for that category

What to do

  1. Check whether recommended_browse_nodes appears as an available attribute for the category.
  2. If the attribute does not appear for the category, this will probably need developer review.
  3. If Omnivore shows the attribute but Amazon rejects it, try a category refresh.
  4. If the issue continues, escalate with the product, category, retailer, and example ticket details.

Amazon Australia validation warning: [16364] - This product has other listing limitations.

Error message

Amazon Australia validation warning:

[16364] - This product has other listing limitations.

What it means

Amazon has applied a listing limitation to the product. This is usually controlled by Amazon Seller Central, not Omnivore.

Common causes

  • Category approval is required
  • Brand approval is required
  • The product does not meet Amazon compliance requirements
  • The product is subject to regulatory restrictions
  • Amazon has detected a policy, safety, labelling, intellectual property, counterfeit, or prohibited product issue

What to do

  1. Ask the retailer to log in to Amazon Seller Central.
  2. Ask them to locate the notification or restriction linked to the SKU or ASIN.
  3. Ask them to review the specific approval, policy, or compliance details shown by Amazon.
  4. If Amazon requires approval or documentation, the retailer must complete that process in Seller Central.
  5. If Amazon gives no useful details, ask the retailer to raise the issue with Amazon Selling Partner Support.

You are receiving this error as you may be adding Offer-Listing(s) or editing a SKU not present in your catalogue or one thats been deleted.

Error message

You are receiving this error as you may be adding Offer-Listing(s) or editing a SKU not present in your catalogue or one thats been deleted. If this was a deleted SKU, wait 24 hours before resubmitting it. If you have tried to add this SKU to the Amazon catalogue before, check your data and correct any errors before resubmitting. If product is being added to a store from another one, it may require few hours for localisation before it is valid. Please check your seller account for progress or any issues.

What it means

This error is misleading. It usually does not mean the SKU is deleted or missing from the catalogue.

The key part is:

“If you have tried to add this SKU to the Amazon catalogue before, check your data and correct any errors before resubmitting.”

In plain English, this means the missing attribute warnings or other validation warnings need to be fixed first.

Common causes

  • Required Amazon attributes are missing
  • Other Amazon validation warnings are still unresolved
  • Amazon has not yet processed the latest product upload
  • The SKU was recently deleted and Amazon has not finished processing the deletion

What to do

  1. Check the product warnings in Omnivore.
  2. Fix all missing attribute warnings first.
  3. Resubmit or wait for the next upload to Amazon.
  4. If all attributes have been added, allow time for Amazon to process the update.
  5. Expect the product to take around 10 minutes to 4–5 hours to show for sale after all warnings are resolved.

Amazon Australia validation warning:[110002] - Unable to Retrieve Media Content for URL 'Access Denied by Server'

Error message

Amazon Australia validation warning:[110002] - Unable to Retrieve Media Content for URL 'Access Denied by Server'

What it means

This warning is only a real issue if the retailer does not already have images in Amazon.

With the new listing API, Omnivore uploads retailer images temporarily to:

https://omnivore-product-images.s3.ap-southeast-1.amazonaws.com/amazon/

Those temporary image files are deleted after a few days. This is not the same as the old listing API issue where the retailer’s website blocked Amazon from accessing image URLs.

Common causes

  • The temporary Amazon S3 image has expired
  • Amazon tried to fetch the temporary image after it was removed
  • Product images need to be recreated for Amazon

What to do

  1. Check whether the product already has images showing in Amazon.
  2. If the product already has images in Amazon, this warning may not need action.
  3. If images are missing, open the product page in admin.
  4. Scroll to Amazon Product View/Admin only.
  5. Click Product images for Amazon S3.
  6. Click Upload All to recreate the images.
  7. If this keeps recurring, reference the Trello task for forcing image recreation when the warning is received.

Your product details aren't complete enough to find a matching ASIN or create a new one.

Error message

Your product details aren't complete enough to find a matching ASIN or create a new one. To fix this, verify your product identifiers (UPCs should have 12 digits, EANs 13 digits, and ISBNs 10 digits) are correct and include all required product information. You can then either search for your ASIN again or create a new one.

What it means

Amazon does not currently have enough valid product data to match the item to an existing ASIN or create a new ASIN.

This warning is often temporary if all other required attributes have already been added.

Common causes

  • Required product attributes are missing
  • Product identifiers are invalid or incomplete
  • Amazon has not yet processed the corrected product data
  • An upload still needs to run to clear the warning

What to do

  1. Check whether all missing attribute warnings have been fixed.
  2. Confirm the product identifier is valid:
    • UPC should have 12 digits
    • EAN should have 13 digits
    • ISBN should have 10 digits
  3. Resubmit the product or wait for the next Amazon upload.
  4. If all required attributes are fixed, allow around 10 minutes to 4–5 hours for Amazon to clear the warning.

You need approval to list in this brand.

Error message

You need approval to list in this brand.

What it means

Amazon requires the retailer to have approval before listing products under that brand.

Common causes

  • The retailer has not been approved to sell the brand
  • The brand name in the retailer product data does not exactly match the approved Amazon brand
  • A product attribute brand overlay is overriding the expected brand value
  • Spelling or capitalisation does not match Amazon’s approved brand name

What to do

  1. Check the brand in the retailer’s product data.
  2. Check whether a product attribute brand overlay is being used.
  3. Confirm the spelling and capitalisation exactly match the retailer’s approved brand in Amazon.
  4. Ask the retailer to check brand approvals in Amazon Seller Central.
  5. If needed, ask the retailer to provide a screenshot of their brand approvals.
  6. If the retailer is not approved, they must request approval through Amazon Seller Central.

This product has been identified as one that is prohibited for sale or violates image guidelines.

Error message

This product has been identified as one that is prohibited for sale or violates image guidelines. We prohibit any sexual or offensive adult product or any listing(s) that may include explicit sexual imagery. For more information, please refer to Seller Central > Policies, agreements, and guidelines > Program Policies > Product guidelines.

What it means

Amazon has blocked the product or ASIN because it believes the listing is prohibited or violates image guidelines.

This can be caused by content uploaded by another retailer on the same ASIN, not necessarily by the retailer using Omnivore.

Common causes

  • Amazon has blocked the ASIN
  • The ASIN contains prohibited material
  • The ASIN contains image content Amazon considers explicit or offensive
  • Another seller’s contribution to the ASIN caused the restriction

What to do

  1. Check whether the product should be blocked from listing.
  2. Ask the retailer to review the ASIN in Amazon Seller Central.
  3. If the retailer believes the block is incorrect, they must raise a ticket with Amazon.
  4. Do not treat this as an Omnivore mapping issue unless the product data being sent from Omnivore is clearly incorrect.

The Listing data provided is different from what is already in the Amazon catalogue.

Error message

The Listing data provided is different from what is already in the Amazon catalogue. The standard product ids (such as UPC, ISBN, EAN or JAN codes) provided matches the ASIN xxxxxxxxx, but some of the listing data contradicts what is already in the Amazon catalogue.

What it means

The product identifier matches an existing Amazon ASIN, but the product data being sent does not match the data already on that ASIN.

Common causes

  • The retailer’s GTIN matches an ASIN with different product data
  • Brand, title, manufacturer, size, colour, or other attributes conflict with Amazon’s catalogue
  • The SKU may need to be linked to the correct ASIN

What to do

  1. Check the ASIN linked to the SKU.
  2. Compare the retailer’s product data with the product data shown on Amazon.
  3. If the ASIN is correct, update the retailer’s values to match Amazon where appropriate.
  4. If the SKU is not linked to the correct ASIN, use the ASIN linking process.
  5. If Amazon’s catalogue data is wrong, the retailer may need to ask Amazon to update the ASIN.

What it means

Amazon could not access the product image URL. This is usually caused by the retailer’s server, firewall, image hosting, redirects, or temporary access issues.

We have temporarily removed your ability to submit listings (creating new offers or new ASINs) because an unusually high number of listings have been created from your account.

What it means

Amazon has temporarily restricted the seller account from submitting listings because of listing volume.

Common causes

  • The seller account created an unusually high number of listings
  • Amazon has applied a temporary listing restriction

What to do

  1. Advise the retailer that this restriction is controlled by Amazon.
  2. Ask the retailer to check Seller Central for account notifications.
  3. Wait for the restriction to clear.
  4. If it does not clear, the retailer needs to contact Amazon Selling Partner Support.

The following attributes are missing for SKU: [manufacturer]

Error message

The following attributes are missing for SKU: [XXXXXXXXX]: [manufacturer]

What it means

Amazon requires a manufacturer value.

Omnivore automatically sends the product brand name in the manufacturer field, so this often means the existing ASIN has a missing or different manufacturer value.

Common causes

  • Existing ASIN has an empty manufacturer value
  • Existing ASIN has a different manufacturer value
  • The ASIN may have originally been created with incorrect data

What to do

  1. Check the brand/manufacturer data for the product.
  2. Confirm whether the product is linked to an existing ASIN.
  3. If the ASIN has missing or incorrect manufacturer data, ask the retailer to raise a support ticket with Amazon.
  4. The retailer should ask Amazon to add or update the manufacturer value.

Please indicate that the item is a variation parent before setting up variation relationships.

Error message

Please indicate that the item is a variation parent before setting up variation relationships.

Along with:

You may not create new variation relationships for this Brand. You are free to add offers to any existing ASIN for this Brand.

What it means

Amazon is rejecting the creation of new variation relationships for this brand.

Common causes

  • Amazon does not allow the retailer to create new variation relationships for the brand
  • The product is not correctly identified as a variation parent
  • Amazon brand restrictions are preventing variation creation

What to do

  1. Check whether existing ASINs already exist for the product and variants.
  2. Check whether the product can be linked to existing ASINs instead of creating new variation relationships.
  3. If no solution is available, submit a support ticket for review.
  4. Ask the retailer to contact Amazon if the restriction is controlled by brand approval or catalogue policy.

Amazon Australia validation error: merchant_suggested_asin is invalid

Error message

Amazon Australia validation error: SKU does not match any ASIN and contains invalid values for attributes required for creation of a new ASIN. New ASIN creation requires the following attributes, for which this SKU provided invalid attribute value(s): merchant_suggested_asin

What it means

The ASIN specified in the linking screen is no longer valid on Amazon.

This can happen when previous GCID errors caused a manual ASIN link in Omnivore, but Amazon later cleaned up duplicate ASINs and the linked ASIN no longer exists.

Common causes

  • The manually linked ASIN is no longer active
  • Amazon removed or merged duplicate ASINs
  • Omnivore is linking to an ASIN that no longer exists

What to do

  1. Check the ASIN currently linked to the SKU.
  2. Search Amazon for the remaining active ASIN.
  3. Remove the invalid ASIN link.
  4. Relink the SKU to the active ASIN in Omnivore.
  5. Resubmit the product.

Please review your selling price and maximum price

Error message

Please review your selling price and maximum price and ensure that your maximum price is greater than or equal to your selling price

What it means

Amazon has flagged the listing because the selling price is higher than the maximum price set in Seller Central.

Common causes

  • Maximum price in Seller Central is lower than the current selling price
  • Retailer pricing changed but Amazon maximum price settings were not updated
  • Amazon pricing protection has blocked the listing

What to do

  1. Ask the retailer to check the SKU price in Amazon Seller Central.
  2. Ask them to check the maximum price value.
  3. Ensure the maximum price is greater than or equal to the selling price.
  4. Resubmit the product after the pricing settings are corrected.

The MAIN image that you have submitted shows a product that is different from the product represented by the ASIN's existing MAIN image.

Error message

The MAIN image that you have submitted shows a product that is different from the product represented by the ASIN's existing MAIN image.

  2. Check whether the SKU is linked to the correct ASIN.
  3. Check the UPC or product identifier.
  4. If the ASIN is wrong, update the ASIN link.

  6. Resubmit the product after the image or identifier issue is corrected.

Your seller account is not approved to offer seller-fulfilled products in this category at this time

Error message

Your seller account is not approved to offer seller-fulfilled products in this category at this time

Error 4400

What it means

The seller may only be authorised to sell the product using Amazon Fulfilment Network, not Merchant Fulfilment Network.

  • Amazon has restricted the seller to AFN
  • Seller-fulfilled offers have been deactivated
  • A policy violation, seasonal restriction, or customer complaint has affected fulfilment permissions
  • The category does not allow the retailer to offer MFN products

What to do

  1. Ask the retailer to check whether the offer is using AFN or MFN.
  2. If the offer is AFN and live, no action is needed.
  3. If the offer is AFN but not live, ask the retailer to contact Amazon Selling Partner Support.
  4. If the retailer wants to list using MFN, ask them to check Performance Notifications in Seller Central.
  5. Ask them to go to Performance > Account Health.
  6. If Account Health says seller-fulfilled offers have been deactivated, the retailer must click Reactivate and submit a plan of action or appeal to Amazon.

Common causes

  • UPC, EAN, or GTIN is not registered correctly
  • Brand name does not exactly match the registered product identifier
  • Brand name is not affiliated with the UPC, EAN, or GTIN
  • Amazon will not allow ASIN creation because the identifier data does not match

  4. Update the product brand to match the registered brand if appropriate.
