Hey @B_R_Pawan_Kumar

May i know how you are initializing an array? are you?? if not then initialize it first.

Tip- Instead of array you should use List :slight_smile:

This seems to be the solution to my concern

Am I initializing the array ?? I do not think so … how do I do that ?

I request you to please guide me on how to Initialize an array of Strings

That should help me as I am not aware of how to create or work with lists

i do apologize for my ignorance

Hey @B_R_Pawan_Kumar

As i said you are not initializing an array here.

first do it like this in an assign activity.

String Mast_Maza = New String(3){}; //3 is size of an array here.

Then rest your workflow steps and it will work for you. :slight_smile: better to use List

Regards…!!
