why i am getting re.error: unbalanced parenthesis at position 0 error here?

Question

i am trying to send some configuration to my netgear switch using ssh with the function send_config_set()

Netgear_M4100_66={'device_type':'netgear_prosafe',
        'host':'172.16.97.66',
        'username':'admin',
        'password':'******',
        }
    

all_devices=[Netgear_M4100_66]
config_commands=['interface vlan 97']

    
for device in all_devices:    
    
    net_connect = ConnectHandler(**device,fast_cli=True)
    net_connect.enable()
    net_connect.send_config_set(config_commands)
    output=net_connect.send_command('show port status all')
    print("\n\n------------- Device {0} = {1} -------------".format(device['device_type'],device['host']))
    print(output)
    print("----------- End ------------")

this the traceback

sre_constants.error: unbalanced parenthesis at position 0`

after looking to all the examples on the internet, this should be working, but unfortunately, it's not . i thought the problem would be with python3.6 so i upgraded it to the newest python3.8 but still getting the same problem.
