This error usually means that DEPNotify was run before, regardless of whether it was successful or not. 


When DEPNotify runs, it creates some files that when present prevent it from running again.  


To get DEPNotify to run again, delete any of the following files that exist on the computer:


/var/tmp/depnotify.log
/var/tmp/depnotifyDebug.log
/var/tmp/com.depnotify.provisioning.done


This can be accomplished with the following commands in terminal:

sudo rm /var/tmp/depnotify.log
sudo rm /var/tmp/depnotifyDebug.log
sudo rm /var/tmp/com.depnotify.provisioning.done


You will also need to flush the policy on the computer in Jamf if you haven't already since the last time it ran.  


History => Policy History, look for Start Depnotify and choose Flush on the right.
