Ensure that the field names and labels you assigned during data labeling match exactly with what you’re expecting in the Validation Station. Even minor differences can cause selection issues.
Document Understanding Configuration:
If you’re using Document Understanding, make sure that your Document Understanding taxonomy is correctly configured to recognize the fields you labeled. Check the data extraction taxonomy settings to ensure it aligns with your labeled data.
Data Extraction Rules:
Review the data extraction rules defined for the fields you labeled. Ensure that the extraction rules are set up correctly to capture the data from the documents.
If you’re working with Document Understanding, make sure that your document definition accurately represents the layout of the documents you’re processing. Any discrepancies between the document definition and the actual document layout can cause issues.
Data Labeling Quality:
Double-check the quality of your data labeling. Ensure that you labeled a sufficient number of examples for each field, including variations that may appear in the documents.
If OCR (Optical Character Recognition) is involved, verify the quality of OCR. Poor OCR results can lead to difficulty in selecting fields in the Validation Station.
Zoom Level and Resolution:
Check the zoom level and resolution settings in the Validation Station. Sometimes, adjusting these settings can help in selecting fields more accurately, especially if the documents have varying layouts.
Validation Station UI Issues:
If you suspect that the issue is related to the Validation Station’s user interface, consider checking for any updates or patches for UiPath that might address such issues.
UiPath Version Compatibility:
Ensure that the version of UiPath you’re using is compatible with the activities and features you’re employing. Updating to a newer version of UiPath may resolve compatibility issues.
Debugging and Logs:
Implement detailed logging in your workflow to track the actions taken in the Validation Station. This can help in diagnosing the issue further.
