genie module or parsers unstable with cat4500 switch

[gopurx]

Experiencing various errors while using pyats genie libs for cat4ks. Are cat4ks supported with this framework? Can someone review below observations and suggest?

Here is the testbed used:
TEST-DEVICE: os: iosxe platform: cat4k credentials: default: password: "%ENV{device_password}" username: "%ENV{device_user}" connections: cli: protocol: ssh ip: 10.1.1.1 custom: abstraction: # added order: # Added - os # Added - platform # Added

python script to connect to device:

from genie.testbed import load from pprint import pprint tb = load('/tmp/testbed.yaml') device = tb.devices['TEST-DEVICE'] device.connect()

Trying to use genie module device.parse("show platform") receiving an error:
