This is an Etsy error, telling you that your SKU does not have a category assigned! Taxonomy is Etsy's term for category.
There are two solutions to this issue!
The most obvious one, would be to assign a category for the Etsy SKU. You can do this on the Edit Listings page for the Etsy SKU.
This is the more comprehensive fix.
You need to ask yourself WHY was the category not assigned upon creation? Typically, this will be because you did not map the Product listing category to the Etsy category in Category Mappings.

Whenever Listing Mirror creates a new listing, it refers to the Product Listing data. This includes the category. Since most categories do not match across marketplaces, some mapping is required. This is where Category Mapping comes in.
Step by Step
- Go to your Category Mapping page, and find the category of the Product Listing (we use Amazon categories for the Product listing, rather than making up a bunch of our own).
- Create the category mapping for Etsy. And while you're here, I'd advise doing this for most, if not all, of your categories on this page.
- Once you've done this, you can contact Support, letting us know that you would like your category mappings applied to your listings that lack a category. We'll flip a switch on our end, and apply your category mappings to all listings without an assigned category.
