pandevice set_zone error

[mrzepa2]

Greetings,

Using pandevice, I am able to add a tunnel interface, give it and IP, comment, and set the virtual router. using the set_virtual_router() function. However when trying the set_zone() function to set the security zone, I get an error. 

<previous code removed>

#Create a network interface object named tunnl.[TunnelID]
tun = network.TunnelInterface(TunnelID,ip=DATACENTER_TUN_INTF,comment=TUN_COMMENT)
#Add the tunnel object to the Template object and create it.
Template_obj.add(tun).create()

TUN_ZONE='internal'

tun.set_virtual_router(DC_VR,refresh=True,update=True,running_config=True)

#everything is good up until this point
tun.set_zone(TUN_ZONE,refresh=True,update=True,running_config=True)

The error I get when I run the code:

Traceback (most recent call last):

File "/Users/mrzepa/opt/anaconda3/lib/python3.7/site-packages/pandevice/base.py", line 2447, in _get_param_specific_info
p = token.format(**{})

KeyError: 'mode'

During handling of the above exception, another exception occurred:

ValueError: While updating variable interface, missing replacement variable mode in path

Any help would be most appreciated. Thanks.
