The SKU data provided is different from what's already in the Amazon catalog

The SKU data provided is different from what's already in the Amazon catalog. The standard_product_id data provided matches ASIN [asin number], but the following data is different from what's already in the Amazon catalog: color (Merchant: 'Merchant name / Amazon: 'Collection'). If this is the right ASIN for your product, update your data to match what's in the Amazon catalog. If it's not the right ASIN, make sure that your data for standard_product_id is correct.

This error might appear when you try to submit a new value for what currently exists in the Amazon catalog. You might not be able to change the values for the products from the Amazon catalogs if the product belongs to a protected brand. As advised from the error message, you should adjust the data for this product in Shopify if this is exactly the needed product.
