ReviseFixedPriceItem API Returning Error [21916582]- Duplicate VariationSpecifics trait value in the VariationSpecificsSet container.

Question

Answer

There might be several reasons for API failure. One of the reasons is that the seller has sent the duplicate values in the VariationSpecificsSet container. Ensure that each variation has a unique combination of values for the specified item specifics. If you're attempting to change the name of a variation specific, use the ModifyNameList container within your call. This allows you to specify a new name for a variation specific while ensuring that the new name and its values are included in the VariationSpecificsSet container, and the original name is omitted.

Here’s a step-by-step approach to troubleshoot and resolve the issue:

1. Review Current Variation Specifics: Use the GetItem call to fetch the current list of variation specifics. This will help you verify the existing names and values.

2. Modify Variation Specifics Names: If you need to change a variation specific name, use the ModifyNameList container. Specify the current name and the new name you wish to use.

3. Update VariationSpecificsSet: Ensure that the VariationSpecificsSet container in your ReviseFixedPriceItem call includes all the new names and their corresponding values, and excludes any old names that you are changing.

4. Check for Required Item Specifics: Use the getItemAspectsForCategory method from the Taxonomy API to ensure that the item specifics you are modifying or adding are not required specifics for the category, as these cannot be changed.

5. Submit the Revise Call: After making the necessary adjustments, submit the ReviseFixedPriceItem call.

By following these steps, you should be able to resolve the issue with duplicate values in the VariationSpecificsSet container.
