Dear all, I was trying out the exercise on UiPath academy on the AI/ML Movie Review practice. I started from scratch and followed the solution step by step, and copied the solution step by step. Everything was working fine until one of the last part “Task for Human Validation” where I get the following error:
Message: An extension of type ‘UiPath.Activities.Contracts.Persistence.IPersistenceBookmarks’ must be configured in order to run this workflow.
Exception Type: System.Activities.ValidationException
RemoteException wrapping System.Activities.ValidationException: An extension of type ‘UiPath.Activities.Contracts.Persistence.IPersistenceBookmarks’ must be configured in order to run this workflow.

at System.Activities.WorkflowApplication.Enqueue(InstanceOperation operation, Boolean push)
at System.Activities.WorkflowApplication.SimpleOperationAsyncResult.Run(TimeSpan timeout)
at System.Activities.WorkflowApplication.BeginRun(AsyncCallback callback, Object state)
If I disable the “Wait for Form Task and Resume”, it works. I check back and forth and couldn’t find any difference between my built from scratch version and that of the one downloaded from UiPath Academy (which works when running from the same machine).
Any help would be appreciated.
