Read Range Error: Object reference not set to an instance of an object

Help
1

Hi, I had used read range in if activity and I put it in the then column within a sequence. There is an error when debugging the file like what stated in this topic’s title.

How can I solve it?

Thank you and best regard.

Did you use Datatable variable in output of Read range activity ?
This error generally occurs because of any missing variable as output OR any null value returned from the variable

Thank you for your reply. There is null value returned from the variable. It solved.

Thank you again.
