I've been receiving error code 8040 and 5461 for a brand that I have successfully received catalog authorization from to create new ASINs. I have been selling the stand-alone ASIN for more than 3 years and I am trying to create a variation and keep getting these 2 error after uploading the flat file.

I have tried open the case with Amazon but the support was not helpful and didn't know how to resolve it. I just to add a new color to my product.

Please help, the Case ID is: 17465919041 and batch ID: 50010020170
