Error Exception



can anyone tell me why this error generates me?
I would be very grateful for your help.


The error is because either the ‘in_TransanctionNumber’ or the ‘WorkItems.count’ variables used in the If statement is null.


but I followed the instructions of the guide, and as you can see they do not say to assign them any kind of value. @Vinutha


@momi_fede,Set in_transactionNumber=1 in the arguments and execute.
