Amazon Error 8058: Some attributes are missing for SKU
If the error you are receiving is like this, without listing any actual attributes:
8058 Error Some attributes are missing for SKU: [###-###]. For more details, see http://sellercentral.amazon.com/gp/errorcode/8058
This error is usually thrown when the seller provides a weight but fails to provide a value for the item_weight_unit_of_measure field. So please provide a value for that field in the listing profile and try again.
Even if your current feed does not contain any value for the weight, it might be that a weight value set in a previous feed or otherwise, so Amazon now required you to submit a valid weight unit, even if you omit the weight value itself.
