I am running below commands on my F5 device using python script

commands = [
    'show sys version',
    'show ltm virtual field-fmt | grep -E "name|destination|status.availability-state|status.enabled-state|status.status-reason"',
    'show sys performance all-stats historical'
]

I am getting error on command show ltm virtual field-fmt | grep -E "name|destination|status.availability-state|status.enabled-state|status.status-reason" while i am able to run this command successfully in my F5 device ..

python error :
