我尝试为此购买联邦快递皮卡，我使用easyPost api。https://www.easypost.com/docs/api
代码运行良好，直到我尝试购买皮卡的那一刻
我的代码

}
但我得到错误
string(137) "{"error":{"code":"PICKUP.BUY.FAILED","message":"Unable to process request<!--Express dispatch returned invalid response-->","errors":[]}}"
对于这个错误，我在互联网上找不到任何东西
为什么不想买皮卡？
如何理解问题所在以及如何解决？
谢谢！
