Intelligent OCR - Train Classifiers and Extractors Activity - Error

Using Studio 2019.4.4

Getting an error: Human validated data not specified (end error message) after the Present Validation Station activity has been completed and it attempts to run the Train Classifiers and Extractors activity. I have all of the input arguments completed on the Train Classifers and Extractors activity and the Keyword Based Classifier activityThe additional error message:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.ArgumentException: Human validated data not specified

  • at UiPath.Shared.Activities.AsyncTaskNativeImplementation.BookmarkResumptionCallback(NativeActivityContext context, Object value)*
  • at UiPath.Shared.Activities.AsyncTaskNativeActivity.BookmarkResumptionCallback(NativeActivityContext context, Bookmark bookmark, Object value)*
  • at System.Activities.Runtime.BookmarkCallbackWrapper.Invoke(NativeActivityContext context, Bookmark bookmark, Object value)*
  • at System.Activities.Runtime.BookmarkWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)*

Figured it out, one of the Input Arguments (Human Validated Data) had the extractionResults object type, not the validation results object type. Once I corrected, the error message disappeared.
