I am trying to run a test workflow on a workflow that contains the Create Form Task activity. However, when it tries to invoke the workflow in the test, I get the following error.

“Determine Unknown Vendor Code - Invoke Workflow File (Subprocesses\Determine Unknown Vendor Code.xaml): An extension of type ‘UiPath.Activities.Contracts.Persistence.IPersistenceBookmarks’ must be configured in order to run this workflow.”

Funny thing is, I do have persistence support enabled in the project settings. Additionally, I have Action Center activities for verifying machine learning extraction results in main.xaml and those work just fine. Has anyone else seen this issue?

Never mind, I thought that create forms tasks didn’t have to be in main.xaml. I hate that this is required, you cannot write any unit tests and the main.xaml gets bloated.
