For the life of me, I can not get a scheduled script to execute weekly every Sunday. Is there anything that looks wrong here in my configuration:

That looks fine to me. Up top is the Status set to Scheduled?

Yes, it is.

You got me. Is it not triggering or just not doing anything? If you set a log.debug first thing in the script does that log show on schedule/manual trigger? Other things would be scrip active, deployment is deployed. Otherwise looks like it should run

timezone mismatch? is 9pm not really 9pm for your time versus server time?

Oh, I think I know what the issue is. It is a timing issue.
