This question was asked at 15:58:00 on August 5, 2025 Beijing time I have successfully created the shipping plan process. When I need to get the label through the https://developer-docs.amazon.com/sp-api/lang-zh_CN/reference/getbilloflading API and upload the shipment ID, the interface returns "errors": [ { "code": "InvalidInput", "message": "FTXGatewayService.getShipment returned error code: 400", "details": "" } ] I tried to call it several times afterwards, and finally I canceled the shipment plan I don't know where to check this problem
