It looks like that relay doesn't include an "ipv6-policy" line in its
server descriptor, and that's what Onionoo puts in its
"exit_policy_v6_summary" field.  If that line is not present, it omits
that field.

I'm including a server descriptor published by that relay and another
server descriptor published by another relay that includes an
"ipv6-policy" line.

Not much we can do in Onionoo here, I'm afraid.

All the best,
Karsten
