5) Missing Attributes manufacturer_minimum_age


The Manufacturer Minimum Age attribute field needs a value, this can be added in Omnivore under Products - On Amazon - Marketplace Attributes Tab. Search on this page using the SKU and scroll across to see the Manufacturer Minimum Age field where you can add your value.
6) The SKU data provided conflicts with the Amazon catalogThe data provided by the retailer is conflicting with what Amazon has in the database. For example  (Merchant: '' / Amazon: '16192'). The retailer can update their content to match Amazon OR petition Amazon to change the data.
7) We could not access the media at URL https://xxxx.com.au/xxx.jpg. A 403 HTTP status code was received. Ensure that the server or firewall configuration is not blocking Amazon servers from accessing the media.Possible Causes
1) Your server or website firewall settings may be blocking access to the Amazon servers when they are accessing your product image URL's. The error can be caused by the Amazon server accessing a large number of your images in a short period of time and triggering rate limiting or blocks.
The solution for this is to allow all product images on your website to be accessed without rate limiting or blocking the Amazon servers. The fix will vary depending on your website and/or server setup so you will need to refer to your developer.

2) This error can be transient and may sometimes clear on its own over time. It is possible Amazon could not access the image at the time the feed was sent. This could be due to temporary network or server issues. Try re-uploading your products to Amazon from the Omnivore Dashboard.

3) If there is an image in the product page in Omnivore, right-click the affected image in the Omnivore product page to open the image in a new browser tab. Check the URL shown and compare it to the URL in the Amazon error message. If the URL's are different, then your website has an HTML redirect. Please refer this to your developer.

4) If no image is showing in Omnivore, Amazon also cannot access the image. You should update the product image/s on your website.

5) This message is now a warning on the product page in Omnivore.  Warnings are in blue not yellow. Omnivore will not make any changes to the listing on Amazon, it will still remain listed, but the warning is there to let you know that they have detected an image URL anomaly on that product.

This error is caused when the ASIN specified in the linking screen is no longer a valid ASIN on Amazon. It can be due to there being previous GCID errors so a manual link to the ASIN was done in Omnivore but Amazon has since cleaned up the duplicates in their data and we are linking to the ASIN that no longer exists.  Please re link to the remaining active ASIN in Omnivore.
32) Please review your selling price and maximum price and ensure that your maximum price is greater than or equal to your selling price

34) Unable to list any product items (check warnings)When you see this error it will appear as a  yellow error message.  Please scroll down and also then check the blue warning messages.  It is likely that every variant has an issue and therefore the product and variants are not listing.

This error occurs when a seller is only authorised to sell products using the Amazon Fulfilment Network (AFN) due to policy violations, seasonal restrictions, or customer complaints. If you are trying to sell using Merchant Fulfilment Network (MFN), the offer will be un-buyable. If you have already chosen AFN as your fulfilment channel and your offer is live for sale, you can ignore this error. However, if you have confirmed that the SKU is listed as AFN and find that the offer is not live, contact Selling Partner Support.

If you would like to list through MFN, verify as mentioned below:

If a policy notification was issued for that ASIN under Performance Notifications, navigate to Seller Central > Performance > Account Health to see listings that were removed due to policy violations and contact Selling Partner Support with the relevant information.

Under Account Health, if it states 'Your seller-fulfilled offers have been deactivated', then click Reactivate and submit a plan of action or appeal the decision to restore seller-fulfilled privileges.



40) Amazon Australia validation warning:

SKU does not match any ASIN and the product data provided is not eligible for ASIN creation. Please check 1) your UPC/EAN/GTIN is registered in the G1 tool or 2) ensure brand name used to list the product is the exact brand name or affiliated with the UPC/EAN/GTIN. If these steps did not work please log into your account and search error code 8566 for further information


This error points to one likelihood that the UPC (barcode, product identifier) is registered to brand called (example) 'Big Dog' but the brand name on the product with the error is 'Big Dogs Bark' which is not what Amazon

is expecting. Also, as per the error also check the UPC G1 tool. Further error code searching in your Amazon Seller Account will also help.

This error occurs when the Shipping Policy names in Omnivore and Amazon do not match exactly, it necessary that they do match and also be the same case.  Please check your shipping policies between the two systems and correct where needed.

WARNING:

Cannot invoke method value() on null object[WILL SHOW A SKU] java.lang.NullPointerException: Cannot invoke method value() on null object.


If an Amazon product has a warning Cannot invoke method value() on null object


java.lang.NullPointerException


This will mean that we are missing something at a category level in Amazon which will need a dev to look at or update.
