I am trying to set a timer for an exception flow in a user input task. I am usin

Hello, I had a similar issue few days ago. Here is the answer from the Appian Support :

"today() or now() is not a valid trigger in a rule event -- rule events are only triggered off of changes to PVs and constants. It will thus only be triggering based on other elements in the expression for the event. You should be using a daily timer event for a daily check; a timer event on a daily check is very quick and efficient.

You can configure your task with a timer and trigger the exception using:
"Skip this node at the date and time specified by this expression: =pv!targetdate"
Your initial approach is not valid in Appian."

Best regards

Hello, appreciate your input. I need to setup this as repeating daily at a certain time.

I got it working with this expression:
=userdatetime(right(tostring((today())),4),left(tostring((today())),1),extract(tostring((today())),"/","/"),8,45,0)
