I keep running into an error when I try to adjust an incoming date field from a Jotform. Jotform, for some reason, doesn't send a time zone with their date field, so in order to get it to land on a calendar correctly, I've been using addhours to do the adjustment. This worked without a problem until suddenly it didn't. No change was made to the form or the incoming data - it still shows up in the incoming feed. If I try to run the flow without adjusting the date/time, it lands on the calendar, just several hours off of the correct time. Now, when I apply the addhours expression to the dynamic incoming date, it errors out and says that it is expecting a string value and is getting a null one. It's not a null value - it shows up correctly in the incoming data. What am I doing wrong?
