How to pass data to napalm_get

I am using following syntax try to get an output for a specific route, however, I am getting errors:

syntax:

results = nr.run(napalm_get, getters=“route_to(‘103.239.128.0’)”)

Error:

AttributeError: ‘IOSDriver’ object has no attribute ‘get_route_to(‘103.239.128.0’)’

I tried multiple different format of the syntax, can’t make it work.
If I just use “route_to”, it ask me to specify destination:

syntax:

results = nr.run(napalm_get, getters=“route_to”)

Error:

vvvv napalm_get ** changed : False vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv INFO
{‘route_to’: ‘Please specify a valid destination!’}
^^^^ END napalm_get ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
