I'm trying to schedule a flow based on an end user's chosen start time (which they'd pick and submit via an FME Server app).
To do this, I've built two flows: one that takes all the parameters (including a scheduled start time) and has a server app built in front of it; and a second one that actually does the heavy lifting and is either called via a webhook or is scheduled by FME Server.
I've tried to be clever and set a HTTPCaller at the end of the first flow to initiate a new once-off schedule in FME Server, but it's always failing with this error message:
"message": "Unauthorized request by user admin due to lack of proper permissions or the object does not exist."
Any ideas? Or even thoughts on better ways to do this?
