ParamsModel Error when changing the OCR language
3023888
Question / Problem:
The following errors
ERROR DAS - ParamsModel::Incomplete line
ERROR DAS - ParamsModel::Unknown parameter
can be seen in the Desktop Automation Service logs after switching the OCR language in Kofax RPA.
Answer / Solution:
Kofax RPA uses the Tesseract OCR engine to capture text from images. By default, Kofax RPA installs the English language for OCR but this can be changed following the instructions in the User Guide.
When following the procedure to change the language make sure to use the traineddata file for the Tesseract version used in your Kofax RPA version.
The errors above are logged when using the traineddata files meant for a different Tesseract version.
Here is the list of Kofax RPA versions and their corresponding Tesseract versions:
Kofax RPA versions | Tesseract version |
10.2 and Earlier | 3 |
10.3 - 11.0 (including for Intelligent Screen Automation) | 3 |
Applies to:
Product | Version |
---|---|
RPA | 10.0 and Later |
