Migration Legacy to Windows Reports Error

[VanjaV]

Hi,

after workflow migration from legacy to windows I get this error:

Expression Activity type ‘VisualBasicValue`1’ requires compilation in order to run. Please ensure that the workflow has been compiled.

at System.Activities.Expressions.CompiledExpressionInvoker.InvokeExpression(ActivityContext activityContext)
at Microsoft.VisualBasic.Activities.VisualBasicValue1.Execute(CodeActivityContext context) at System.Activities.CodeActivity1.InternalExecuteInResolutionContext(CodeActivityContext context)
at System.Activities.Runtime.ActivityExecutor.ExecuteInResolutionContext[T](ActivityInstance parentInstance, Activity1 expressionActivity) at System.Activities.InArgument1.TryPopulateValue(LocationEnvironment targetEnvironment, ActivityInstance activityInstance, ActivityExecutor executor)
at System.Activities.RuntimeArgument.TryPopulateValue(LocationEnvironment targetEnvironment, ActivityInstance targetActivityInstance, ActivityExecutor executor, Object argumentValueOverride, Location resultLocation, Boolean skipFastPath)
at System.Activities.ActivityInstance.InternalTryPopulateArgumentValueOrScheduleExpression(RuntimeArgument argument, Int32 nextArgumentIndex, ActivityExecutor executor, IDictionary2 argumentValueOverrides, Location resultLocation, Boolean isDynamicUpdate) at System.Activities.ActivityInstance.ResolveArguments(ActivityExecutor executor, IDictionary2 argumentValueOverrides, Location resultLocation, Int32 startIndex)
at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)

How do I know which activity in workflow is making this problem?
How do I find the problem in the workflow in order to change it?

Thx and kind regards,
Vanja

Hello @VanjaV
Try to Update all the packages from Manage packages.

Hi @VanjaV

This issue is regarding the Double Quotation **“”**in all the activity. You need to update all the double quotation or re enter the expression again

Check out this thread

2022.10 Release is causing Compilation errors for Date conversions

Hi @Marco_Willigenburg Check the Double Quotation " in the Date Try with this expression "\kotvs003\KOT\Works\Poldat\Controlling\PBI\MPZW\InventoryPBI\Material Usage Per Month\Material Usage Per Month"+now.AddMonths(-1).ToString("MMyyyy")+".xlsx" Check out this thread Regards Gokul

thx. How do you know this is the case?

I migrated the project and published it successfully.
When running it with UiPath Assistant it reported the error above.

Kind regards, Vanja
