Error message since upgrade 2.7.0 to 2.7.2 and enable Kea DHCP

M0L50N

Hi.

Tonigh, I updated my pfsense 2.7.0 to 2.7.2. By the way, I was unable to obtain the update but follow some trick on forum to update repository and that worked.

Right after the update, I enabled the Kea DHCP in Advanced/Networking. When I cliked "save", I got this PHP error message :

[19-Aug-2024 23:24:23 America/New_York] PHP Fatal error:  Uncaught TypeError: implode(): Argument #1 ($array) must be of type array, string given in /etc/inc/services.inc:1411

#4 {main}
  thrown in /etc/inc/services.inc on line 1411
No FreeBSD crash data found.

I login back to my pfsense and see that Kea DHCP was enable. Going in my DHCP server to adjust some WINS/DNS and when I click "Apply change" I got another PHP error

I'm unable to save my DHCP change ... any idea about that problem?

Thanks

@M0L50N - Update

Just for info, If I switch back to ISC DHCP, everything works normally and I can update and start my DHCPD service ... When I was in Kea mode, I was unable to start Kea-DHCP4 service

To be operationnal for tomorrow, I just forget the idea to change DHCP mode to Kea for now ... but if you have idea to help me diagnose this, this would be really appreciate!

Thanks!
