Present Validation Station Method Not Found

I am using the ML extractor and have been able to have the present validation station activity directly after my data extraction. Now when I try to run the process it throws:
Present Validation Station: Method not found: ‘UiPath.DocumentProcessing.Contracts.Dom.TextType UiPath.DocumentProcessing.Contracts.Results.ResultsValueTokens.get_TextType()’.

I am utilizing the enterprise trial.
Does anyone know how to fix this so that the Present Validation Station will work properly?

To resolve this issue, you need to ensure that both libraries are updated to the same version. Here’s how you can do it:

  1. In UiPath Studio, open the “Manage Packages” window by clicking on the “Manage Packages” button in the “Activities” panel.
  2. In the “Manage Packages” window, click on the “All Packages” tab and search for “UiPath.DocumentProcessing.Contracts”. Click on the package and check if the version installed is compatible with the version of the UiPath.IntelligentOCR.Activities package. If not, update it to a compatible version.
  3. Next, search for “UiPath.IntelligentOCR.Activities” and update it to the latest version that is compatible with the version of the UiPath.DocumentProcessing.Contracts package you just updated.
  4. After updating the packages, restart UiPath Studio and try running the process again. The “Present Validation Station” activity should work properly now.

@Shubham_Kinge all of my packages are updated to the latest versions. If I try to downgrade UiPath forces the package to update again. Thoughts? Thank you!

Hi @james.althoff ,

Is it updated to the latest stable versions or does it have preview versions ?
