Error: This product was not processed.

Description:

Error: This product was not processed. Does it have at least one of these: (listing_id, parent_sku, sku)?

This error could mean one of two things when you are uploading new listings to Etsy.

1. You are missing both parent_sku and sku
2. You have duplicate skus for the same parent_sku

Solution:

1. Add parent_sku and sku to your products
2. Rename the duplicate sku that are under the same parent_sku
