hi,everyone,i need your help now .
i used assign activity to change the value of a dataTable’s cell
like: row(“column name”)=“string variable”;
i have also seen the answer to the same or similar question in the forum,and i am sure that each one i used was not null; i checked them by Is DbNull.value,and i also used message box to output them.
there is the log message:
14:00:53.6493 => [ERROR] [UiPath.Studio.Shared.Logging.OutputLogger] [24] Assign: Exception has been thrown by the target of an invocation.
But,when i try to write range my dataTable to the excel file then read excel again before using assgin to change value,it will be ok with assign
could you give me some suggestion?

Make sure the column name exactly matches in the assign activity.
