Hi,

The error which you are facing might occur due to the document doesn’t have any classifications.

I have tried earlier by changing OCR methods to resolve the issue. Please refer the below thread it is related to Intelligent OCR. it would help you on the document understanding too. thanks.

Hi @Seema_Jethe ,

Could you please verify in run time are you getting the classifications for the document or not. the error is showing like we are getting empty.

and also please tell me which OCR method you are using?

i verified using a message box activity and while executing the workflow the document is not getting classified and throwing the same error as index was outside the bounds of array. Below is the screenshot

omnipage OCR is ideal OCR engine for document understanding. Could you try with other OCR’s too and also try with different keywords as well.
