1. "This item is either not handmade, vintage, or a craft item."
If you say your item is made by someone else but it's not a supply or craft tool (which may be the case with your listing). Etsy expects you to make your items yourself, except when it's a supply or craft tool.
When you choose a supply or craft tool category for your item, and still indicate it as not a supply or craft tool.
2. "All combinations of property values must be supplied"
This error occurs if you have a product that varies on size and color, but do not have a full size run of each different color. For example, if you have three sizes for the black shirt variation (S, M, L), but only two sizes of the blue shirt variation (S, M). This discrepancy will causing Etsy to reject Sellbrite inventory syncs and generate this error.
To fix, you will need to add additional size or color variations (even if you do not carry them) so that each variation has the same amount of color/size options. Ex: add Size L as an option for the blue shirt with inventory of 0. Now both colors have 3 size options.
3. "Invalid Shipping Data"
When using calculated shipping profiles, Etsy does not accept weights over 70 pounds and requires the length to be the largest package dimension.
To fix this, on the listing under the Shipping & Returns tab, either edit the weight to under 70 pounds or update the length to the largest dimension. You can then republish the listing.
