Я пытаюсь создать тестовую метку из Shippo, однако получаю ошибку оценки

Однако я получаю эту ошибку, что я не знаю, что это значит:

Фатальная ошибка: Uncaught Shippo_InvalidRequestError: {«rate»: [«Это поле обязательно для заполнения.»]} В /home/****/shippo/lib/Shippo/ApiRequestor.php:100 Трассировка стека: # 0 / home / * *** / shippo / lib / Shippo / ApiRequestor.php (154): Shippo_ApiRequestor-> handleApiError (‘{«rate»: [«This …’, 400, Array) # 1 / home / **** / shippo / lib / Shippo / ApiRequestor.php (59): Shippo_ApiRequestor -> _ interpretResponse (‘{«rate»: [«This …», 400) # 2 / home / **** / shippo / lib / Shippo / ApiResource.php (107): Shippo_ApiRequestor-> request (‘post’, ‘/ v1 /action …’, Array) # 3 /home/****/shippo/lib/Shippo/Transaction.php(14) : Shippo_ApiResource :: _ scopedCreate (‘Shippo_Transact …’, Array, NULL) # 4 /home/****/public_html/.ship/print/done/index.php(65): Shippo_Transaction :: create (Array) # 5 {main} добавлено в /home/****/shippo/lib/Shippo/ApiRequestor.php в строке 100

Я также получил похожее сообщение о поле посылки, поэтому я изменил в посылках сценария PHP на parcel. Это пример кода из https://github.com/goshippo/shippo-php-client/blob/master/examples/basic-shipment.php

Мой код:

<?php

Shippo::setApiKey('****');
