If someone removes all rules, leaving only automatic rules like the anti-lockout rule and bogons, this error can occur.

I couldn't replicate this one on:
SG-3100
2.4.4-RELEASE (arm)
built on Thu Sep 20 09:33:19 EDT 2018
FreeBSD 11.2-RELEASE-p3
I tried with a different type of rules with and without aliases. If there is a specific way how to replicate it, please provide more details.

You have to delete all of the rules in the config so it only has <filter></filter>
So you'd have to hit it from LAN with the anti-lockout rule passing you through.

Was able to replicate this after verifying <filter></filter> in config, connecting on the Anti-lockout rule, and trying to add a new firewall rule on LAN I received this error when the GUI failed:

Upgraded to Current Base System 2.4.5.a.20181120.0855, retested with same steps, was able to add new firewall rule without issue.
Confirmed resolved.

Any way to fix this manually? (i.e. if I don't want to update to dev)
