traceroute and mtr fail with NoneType' object has no attribute 'route'

[sherif84]

i'm trying to utilize the traceroute and mtr function, however I consistently get an error

AttributeError: 'NoneType' object has no attribute 'route'

it works fine with the scapy package but fails with kamene

kamene version : 0.32
Scapy : 2.4.0

>>> from kamene.layers import inet
>>> import kamene
>>> kamene.layers.inet.traceroute(["www.microsoft.com"])
