I ran into the problem that all of my settings in my proccesflow and task were correct however the task in my processflow did not output the variable into my process variable. The reason why this was happening is because the await result of my task was set to No. This caused the report not to wait till the task was done and get a parameter to print my report.
I would like to get a validation that im using a process action after my task/ report and that the followup action has a variable which is not waited for in my next action.
