While working on a new flow today, I brought in the 'wait' action and inputted 4 seconds and am receiving an error message stating "Parameter 'Duration': Expression must contain a 'Numeric value'.".
What changed as any value from 1 to Infinity is a numeric value, but PAD is not recognizing it for the moment.
BTW, in a different flow I finished earlier this week, I'm used the "wait" action with no issues. Other flows with 'wait' action have not bombed or broken and they are fully automated with a timer and the ones scheduled to run today ran with no issues or errors.
