The message is not friendly and there is no key in my mind. The stack trace shows seem a bit more details:
at Microsoft.SharePoint.Library.SPRequestInternalClass.AddOrUpdateItem(String bstrUrl, at Microsoft.SharePoint.Library.SPRequest.AddOrUpdateItem(String bstrUrl, --- End of inner exception stack trace --- at Microsoft.SharePoint.SPGlobal.HandleComException(COMException comEx) at Microsoft.SharePoint.Library.SPRequest.AddOrUpdateItem(String bstrUrl, at Microsoft.SharePoint.SPListItem.AddOrUpdateItem(Boolean bAdd, at Microsoft.SharePoint.SPListItem.UpdateInternal(Boolean bSystem, at Microsoft.SharePoint.SPListItem.Update()
Basically I just add new item by programmatically and it throw exception.
Solution: I found the reason and resolved this with my situation. In my list, there is a column that work incorrectly. I could not access the value of that column, eventhough I could get the details of its. I remove that column out of the list's schema and then re-add into list. It worked!
