BR works when run manually, but not through Task Schedule

Is that all of your code? 

No, the BR is much longer, however the Execute Parse and Transform is the line that fails.

Have you verified what wfProfileName, wfScenarioName and wfTimeName are set to?  Have you checked that wfUnitClusterPk is set to something other than Nothing?

Yes I have validated all of that. 

Here is the full code up to there:

				Dim jobLog As New Text.StringBuilder
				Dim returnValue As New List(Of Object)
				Dim jobStatus As Boolean = True
				Dim wfUnitClusterPk As WorkflowUnitClusterPk = BRApi.Workflow.General.GetWorkflowUnitClusterPk(si, wfProfileName, wfScenarioName, wfTimeName) 
				Dim ProfileKey   As Guid    = wfUnitClusterPk.ProfileKey
				Dim ScenarioKey  As Integer = wfUnitClusterPk.ScenarioKey
				Dim TimeKey      As Integer = wfUnitClusterPk.TimeKey					
				Dim wfProfileInfo As WorkflowProfileInfo = BRApi.Workflow.Metadata.GetProfile(si, wfProfileName)
				log.AppendLine($"*********************> {wfProfileInfo.Type}")
				jobLog.AppendLine($"{Environment.NewLine}============ Workflow Start ============")
				log.AppendLine($"{Environment.NewLine}============ Workflow Start ============")
				jobLog.AppendLine($"       {DateTime.Now.ToString("MM/dd/yyyy hh:mm:ss tt")} UTC       {Environment.NewLine}")
				log.AppendLine($"       {DateTime.Now.ToString("MM/dd/yyyy hh:mm:ss tt")} UTC       {Environment.NewLine}")
				log.AppendLine($"  Workflow:                {wfProfileName}")
				log.AppendLine($"  Scenario:                {wfScenarioName}")
				log.AppendLine($"  Time:                    {wfTimeName}") 
				log.AppendLine($"  WfPk:                    {wfUnitClusterPk}")
				log.AppendLine($"  ProfileKey               {ProfileKey}")
				log.AppendLine($"  ScenarioKey              {ScenarioKey}")
				log.AppendLine($"  TimeKey                  {TimeKey}")
				log.AppendLine($"  ----------------------------------------") 
				log.AppendLine($"  Load & Transform:        True")
				log.AppendLine($"  Validate Transformation: {valTransform}")
				log.AppendLine($"  Validate Intersections:  {valIntersect}")
				log.AppendLine($"  Load Cube:               {loadCube}")
				log.AppendLine($"  Process Cube:            {processCube}")
				log.AppendLine($"  Run Confirmation:        {confirm}")
				log.AppendLine($"  Run Auto Certify:        {autoCertify}")
				log.AppendLine("=======================================" & Environment.NewLine)	

			
				'---------------------------------
				'   Parse and Transform:
				'---------------------------------
				Dim ImportInfo As New LoadTransformProcessInfo 
				Try
					log.AppendLine($"Here 1 {wfUnitClusterPk}")
					ImportInfo  = BRApi.Import.Process.ExecuteParseAndTransform(si, wfUnitClusterPk, "", Nothing, TransformLoadMethodTypes.Replace, SourceDataOriginTypes.FromDirectConnection, False)
					log.AppendLine("Here 2")
				Catch ex As Exception
					log.AppendLine("Import Done - Status: " & ImportInfo.Status & " - RowCount: " & FormatNumber(ImportInfo.RowCount, 0,,,-1)) 
					log.AppendLine(ImportInfo.ErrorMessage)
					log.AppendLine("------------------------------")
					log.AppendLine(ex.GetBaseException.Message.ToString.Trim)
				End Try	

All of the log.Appendline statements show all of what you are asking about.  The first thing I checked before coming here is that all of the variables are populating correctly (Troubleshooting 101).  I am testing in a new app to see if it is an issue with the Task Scheduler in this app.  I copied code that is working fine in Prod back to Dev to see if it would work and it does not work in Dev.  I was hoping that someone had seen this behavior with Task Scheduler before.
