System.InvalidOperationException	If the ArcGIS.Core.Data.UtilityNetwork.Terminal in any ArcGIS.Core.Data.UtilityNetwork.Element in TraceArgument.StartingLocations, TraceArgument.Barriers or TraceArgument.FilterBarriers is null and the associated ArcGIS.Core.Data.UtilityNetwork.TerminalConfiguration has multiple terminals.
