Ebay api BulkDataExchangeRequests＆ReviseInventoryStatus：缺少必需的容器

Question

嘗試修改列出的產品數量時，我遇到了BulkDataExchangeRequest/ReviseInventoryStatus（使用Large Merchant Sevices api）的一些問題。爲了上傳和處理BulkDataExchange xml（createUploadJob，uploadFileRequest，startUploadJob），我成功地完成了所有先決條件請求，但產品的數量未在eBay商店中修改。我發現爲了獲取xml本身的錯誤，而不是上傳作業，我必須使用DownloadFileRequest，但我無法修復它返回的錯誤。對於我嘗試使用ReviseInventoryStatus修改數量的3種產品，我收到了錯誤代碼爲21916253的'Missing required container'。我檢查了我發送的xml，但我無法弄清楚究竟是什麼不見了。這裏是XML，任何提示，將不勝感激：

<?xml version="1.0" encoding="UTF-8"?>

</BulkDataExchangeRequests> 

這裏是DownloadFileRequest響應：

字段名稱是區分大小寫的。我在您的請求中發現了幾個都是小寫字段的字段。例如，<inventorystatus>應該是<InventoryStatus>，並且<itemid>需要是<ItemID>。
