這是我在將自定義工作流程部署到表單庫時從Sharepoint收到的錯誤。工作流程非常簡單，不會做任何事情。我正在閱讀一個infopath表單，但是已經刪除了所有非必要的代碼，看看我能否實現它。據我所知，其他工作流程是好的（我在同一個盒子上開發了其他工具，它們完好無損並且功能正常）。工作流的設計視圖如下：成功創建一個任務後，會出現錯誤：在TrackedRequests中找不到請求。我們可能會在不同線程上創建和關閉網頁

錯誤。這導致我相信while循環有一個問題，它正在等待一個布爾變量變爲true（最初設置爲false）。通常，當任務以任何方式改變時，改變的事件將觸發並將變量改變爲真，然後工作流程將繼續。我收到此錯誤在這個工作流程的開始：

我搜索高，低解釋，但無法找到任何具體解決這個問題。這真的是一個簡單的工作流程，沒有什麼特別的事情......也許它是它所附帶的表單庫？
