Shape of passed values vs indices imply

code:

import sadf
from sadf import fieldgroups as fg
cmd = sadf.SadfCommand()
cmd.field_groups = [ fg.Network(dev=True) ]
report = cmd.run()

Error:

After more research, I think this is due to the way docker is creating network interfaces, I'm guessing the dynamic nature of the interfaces being created/removed is the problem...
