我正在尝试在添加新项目但获得关注时更新项目安全性。如何从这个跟踪中找到问题？

这是我的功能，

@Dmitry Kozlov 建议的新代码，但仍然是相同的错误

尝试从您以提升的权限打开的 Web 获取列表项并使用它：

SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite site = new SPSite(lstItem.Web.Site.ID, token))
    {
        site.AllowUnsafeUpdates = true;
        using (SPWeb web = site.OpenWeb(lstItem.Web.ID))
        {
           web.AllowUnsafeUpdates = true;

           // Get list item here:
           var newListItem = web.GetListItem(itemUrl);
           ...
        }
    }
}
