Can you send the raw XML call that is causing the error (with username removed)?
Thanks.
And this would be found where?
Been doing some testing and this is a weight issue. If I set everything system wide to either pounds or ounces and adjust weight classes and product weight accordingly, it throws the error. If I mix weight classes the error is package exceeds 70lbs. I'm working with an item that weighs 10.25 oz. with a quantity of 7 pcs in the cart.
Weight classes when default system and usps weight is pound
Pound = 1
Ounce = .0625
Weight classes when system and usps is set to ounces
Pound = 16
Ounce = 1
According to the USPS extension, weight must be calculated in pounds
And to make matters worse, USPS is doing an API update in a few days and in Jan 2017 all legacy calls will be obsolete and not work anymore. So if there is any legacy in this extension, it will globally break. Gotta love the Postal Service.
Ever onward with testing.
