我正在使用SharePoint PNP库以编程方式创建现代页面，在其中创建Fileviewer，然后将其源设置为文档库中存在的文件。
由于某种原因，我可以看到在新创建的页面内创建的fileviewer webpart，但是没有预览文档。我收到以下错误。
对不起，出了点问题 该项目不存在。可能已被其他用户删除。
我尝试设置所有属性组合。有人可以帮助我创建和设置Modernpage的Fileviewer Webpart的源文档吗？
var page = context.Web.AddClientSidePage(pageName, true);
var temp = page.AvailableClientSideComponents().ToList();
var fileWebPart = new ClientSideWebPart(temp[6]);//6 is fileviewer webpart component, will clean this later.
