Issue: Amazon Buy Shipping does not work for us when trying to create shipments using the following services:
- USPS Ground Advantage (<1lb or 1lb to 70lb)
- USPS Ground Advantage Cubic
There is a window regarding purchasing label from carrier, it disappears and the label is not generated. On Amazon there is no update with tracking or a label made. This is occuring on any order with these services.
Related Issue: If Amazon Buy Shipping Ground Advantage (any version) is in a batch during the batch processing, the batch will immediately fail all orders.
As of today if we attempt to create a label as Amazon Buy Shipping - USPS First Class Mail it returns an error stating:
The purchase request parameters are invalid, please call with the correct parameters or make another call to check eligible options (Bad Request, Carrier Error Code: InvalidInput). (400, 38c83795-07fc-4814-b7cb-6987122f7006)
