Assign activity error - Assign: Object reference not set to an instance of an object

[RafMil91 (Rafał Miller)]

Hello,

can anyone have any idea why I am getting error on this particular activity? Please find below what I am exactly assigning:

ls_account_numbers(account_counter) = row(“My_column”).ToString

ls_account_numbers is an array of string.

Regards,

You need to initialize the array. Please refer the below link

Initialize String list

Hi, You have to make the difference between String Arrays and String Lists. How to initialize both : myStringArray = new System.String(){} myStringList = new System.Collections.Generic.List(Of String) Best regards, Mustafa

There might be a chance of row(“My_column”).ToString returning null hence you are getting this error, Check the value before you assign.
