When you configure a workflow start rule for a SharePoint list that does not have the Item content type, an error occurs. The Item content type is the default content type for all SharePoint lists, so this only happens if you removed it from your list.

Error Message

You see the "Oops! An error has occurred" message in K2 Designer.
