HI @Shanmathi Have you replaced your double quotes in that activity? You need to check and replace all the double quotes in the properties of the activities Regards Sudharsan

Thanks @Sudharsan_Ka , After declaring a variable to the Image field in Tesseract OCR. It worked. Now, it shows Read PDF With OCR: Object reference not set to an instance of an object.

Can you show the variables you assigned? @Shanmathi

Try initializing the variables that you have used before the read PDF with OCR @Shanmathi

Sure @Sudharsan_Ka . [image] Output text as ocrText and Image as image in tesseract OCR.

Use Assign before Read PDF with OCR and try once @Shanmathi ocrText=“”

[image] @Sudharsan_Ka Even after assigning, I face the same issue.

Assign for image too and try @Shanmathi [image]

And also can you check the pdf file is available in the project folder and give the absolute\full path of the pdf file and check again @Shanmathi

And also please change the variable name of image datatype variable @Shanmathi
