Hello, I am a new seller and I was trying to add new products via flatfile,
I fill out everything I need but I keep getting the same error on my parent sku, child skus have no error.
It just tells me
"Error Code 4000000 "
"An internal error has occurred. Please try again."
Therefore even though all my child skus are separated instead of being under my parent sku.
Since it tell me to try again I have reuploaded multiple times.
Being frustrated I contacted Amazon seller support, and they kept giving me the run around saying they'll need to send this to a specialist after putting me on hold for 40 mins. Besides that, I finally get an response from the specialist and they wrote

Hello from Amazon Selling Partner Support,
My name is Suman and I will be looking into your query.
From your correspondence, I understand you are facing error with the feeds upload for the batch ID 50016020194.
I would like to inform you that our internal team has completed the review, and they have stated that no error found anymore for the SKU's, and they have suggested that you should re-upload the feed file and make sure all column required is fill out."
I feel very stuck. Is there anybody that can help me?
