I have a PI Notification which triggers correctly every night before midnight. In the design section, I have around 10 "Value At Start Time" attribute data.
In the HTML Preview I see the correct values populate. When I send a test message, I also see the values populate correctly.
The only issue is at night when the event frame triggers and I receive the email, all the values show NO DATA.
This has been happening recently. I have to restart the PI AF server and it will work fine for a couple days and then NO DATA will show up again.
Any thoughts on why this might be happening?
