Hi @thanapat
Delete the currently used variable, click on the tesseract OCR & create a new variable in the properties panel.
Edit: Create a new image variable in the properties panel.
Hope this helps,
Best Regards.
Hi @thanapat
Usually Tesseract OCR Image property accepts Image Variable, check below for your reference
As per the error you are passing a String variable instead of Image type variable
Check if you are not passing String(), also check if there is another variable / Argument with the same name
Hope this may help you
Thanks,
