尝试将 PDF 发票上传到亚马逊 MWS 会导致错误：“上传发票时请仅提供一个有效的商城”

Question

我目前正在尝试弄清楚如何使用 php/curl 将我自己的发票 pdf 文件上传到亚马逊 MWS： 1.) 使用操作将 pdf 上传到亚马逊 MWS：SubmitFeed 和 FeedType：UPLOAD_VAT_INVOICE 这是通过 FeedSubmissionId 给出积极响应

2.) 获取 Feed 提交结果，该 FeedSubmissionId 报告错误 79523“请在上传发票时仅提供一个有效的市场。”

所以我假设我的上传工作不正常，但我找不到错误。

亚马逊的这个 PDF 文件的第 21 页描述了错误代码：VAT Calculation Service (VCS) Developer Guide

到目前为止，我已经花了 2 天的时间试图解决这个问题，但我在谷歌上找不到任何关于它的信息。希望这里有人可以帮助我。谢谢！

代码如下：

没有 XML 可与此提要一起发布。 FeedContent (CURLOPT_POSTFIELDS) 是 PDF 的内容 ($pdf_feed)
