What must be specified in order to avoid an error during the Read PDF with OCR activity?

To successfully execute the Read PDF with OCR activity in Robotic Process Automation, it is essential to specify the OCR engine to be used. Different OCR engines may have unique capabilities, features, and levels of accuracy, so selecting the appropriate one aligned with your document characteristics is crucial for optimal performance. This specification ensures that the activity can process the text from the PDF correctly, translating the images of text into machine-readable data.

Other aspects like the destination of the file or user permissions can be relevant for process configuration but do not directly impact the success of the OCR operation in itself. The OCR engine specifically addresses how the content within the PDF is interpreted, making it the key requirement to avoid errors during this particular activity.
