pfSense

Tested on the latest 23.01 (built on Tue Nov 01 06:05:26 UTC 2022)

I enabled FRR with simple settings (Default Router-ID and Master Password) but when I added simple Route-map 'EBGP_IN':
Action: Permit
Prefix-list: Allow All
Sequence: 10

FRR crashed.

I see (attached 'frr_route_map_menu.png')
Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/pkg.php:484 Stack trace: #0 {main} thrown in /usr/local/www/pkg.php on line 484 PHP ERROR: Type: 1, File: /usr/local/www/pkg.php, Line: 484, Message: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/pkg.php:484 Stack trace: #0 {main} thrown
