Please help. Thank you!
Set repeat forever property to False. Also verify that in_TransactionItem has some value
What do you mean by in_TransactionItem has some value? Should I put 1? or remain empty?
in_TransactionItem is an input argument so it has to have some value from its parent workflow. Also the other error you showed is because of the selector of Attach Browser activity.
