Word Activity System Error

Help
1

Good afternoon,

When deploying the robot in production, the following error appears:

System.Xaml.XamlObjectWriterException: Cannot create unknown type ‘{http://schemas.uipath.com/workflow/activities/word}WordApplicationScope’. at UiPath.Core.Activities.InvokeWorkflowFile.EndExecute(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

However, when deploying it in the development machine , this does not happen and it works.
It is an activity related to opening a Word document.

We have checked and the version of the programs and the activities packages are the same in pro and development.

Does anyone know how could this ve resolved?

Thank you very much in advance,

Kind regards,

Monica

@Monica_PC - What is the version of UiPath you are using? Can you also verify if the same version of Word is installed on both the machines (dev and prod) and the package dependencies and package versions are same in both?

Hi @Monica_PC

Are you deploying from Orchestrator? If so, the activity feeds are not available for Orchestrator. You should try manually copying the packages from the Studio local feed to the place where Orchestrator downloads them. If you look on the forum for your error message, you will find plenty of references for the phrase

Cannot create unknown type
