I am getting the following error as in the snap please do needful to resolve it.
@HeartCatcher This might be because the variable or argument has no value. Please run the process in debug mode and see exactly where it is coming
the argument has no value that might be the reason kindly recheck and debug step by step
Check the Invoke Login Work flow Arguments, debug and do a step into for each Activity and check the Values.
Thanks
