Welcome to the Community @Gopikrishna_S

you are assigning that parameter a value at run time? may be after extracting from somewhere?

Before assign check if it is null or empty


Welcome to our UiPath community.

Can you show us screenshot of expression you are using in Assign activity.

I guess one of the variable is empty here - Flight_No or Location or Piece_Val. Because of that you are getting that error. Can you check the whether value is empty or not before Assign activity.

yeah bro Correct

But I am getting values from column,first two column dont contain values but other column contain values I want to use this variable to remove values from Description variable


Check whether variable holds any value or not. If it is not empty then replace it with empty else not.
