I have created a testing shipment in sandbox using create_and_buy_label API and the shipment is created with easyship_shipment_id , then I used the easyship_shipment_id to get the label from https://api.easyship.com/label/v1/labels, but it returned error:
{"message":"Shipments not found or labels already requested: ESUS10018758","errors":["Shipments not found or labels already requested: ESUS10018758"],"labels":[],"total_cost":null,"available_balance":-1673.52}

Please kindly advise what's the problem, Thanks!
