这是我在将自定义工作流程部署到表单库时从Sharepoint收到的错误。工作流程非常简单，不会做任何事情。我正在阅读一个infopath表单，但是已经删除了所有非必要的代码，看看我能否实现它。据我所知，其他工作流程是好的（我在同一个盒子上开发了其他工具，它们完好无损并且功能正常）。工作流的设计视图如下：成功创建一个任务后，会出现错误：在TrackedRequests中找不到请求。我们可能会在不同线程上创建和关闭网页

错误。这导致我相信while循环有一个问题，它正在等待一个布尔变量变为true（最初设置为false）。通常，当任务以任何方式改变时，改变的事件将触发并将变量改变为真，然后工作流程将继续。我收到此错误在这个工作流程的开始：

我搜索高，低解释，但无法找到任何具体解决这个问题。这真的是一个简单的工作流程，没有什么特别的事情......也许它是它所附带的表单库？
