Я создаю задачу рабочего процесса ListItem в SharePoint 2013. Рабочий процесс прекрасно работает, когда я добавляю элемент списка создается задача, и нет никакой ошибки. Однако, когда я обновляя элемент кода рабочего процесса дает мне эту ошибку:<nativehr> 0x8102009b</nativehr><nativestack></ nativestack> Workflow Sharepoint 2013
<nativehr>0x8102009b</nativehr><nativestack></nativestack>
