Hello!
The error message tells you that you are passing something strange to
the condition on line 360. What do you have on line 360?

Hi there,
I'm using the template from
https://github.com/neptune-networks/peering/blob/master/out/router.fqdn.example/bird.conf <https://github.com/neptune-networks/peering/blob/master/out/router.fqdn.example/bird.conf>
for my filters, and I'm getting argument related errors in logs.
What's the issue with those filters?
P.S I need to find a guide on how to do bird2 and RPKI as well.
