Automation Stitch (trigger= schedule) , (action = script CLI)

Hello, 

I have configured an automation stitch that, each 1 hour it flushes IPSEC tunnel

(((config system automation-trigger
edit "Restart_script"
set trigger-type scheduled
set trigger-hour 1
next
end

config system automation-action
edit "Restart_script"
set action-type cli-script
set script "diagnose vpn tunnel flush VPN_****"
set accprofile "super_admin"
next
end )))

But the stitch not working! It's supposed to get triggered each one hour, but the trigger count is 0.

Is anybody familiar with it? 

help me please.
