Overview

Previously even if we didn't provide any variable name for the OCR actions that were extracting some texts and saving them into a vriable the action passed successfully which was a bug. Now I have added the check to see, if the variable name is empty then it will throw an error

if var_name == "":
        CommonUtil.ExecLog(
                sModuleInfo, "Please provide a variable name to store the extracted value", 3
            )
        return "zeuz_failed"

This check has been added to the following functions

• ocr_get_value_with_coordinates
• ocr_get_value_with_image
• ocr_get_value_with_text
