Pihole V6 dhcp option 249 (network route) not sent after upgrade?

[cprabel]

Just upgraded to pihole v6 and it seems that my previous dhcp configuration was not fully upgraded

Previously with pihole v5 i added a dhcp option 249 in dnsmaq conf file to advertise "another" network route 172.17.19.0/24 with gw 192.168.1.252 cf. config below (bold) :
interface=eth0
bind-interfaces
dhcp-range=tag:eth0,192.168.1.1,192.168.1.216,24h
dhcp-option=eth0,option:router,192.168.1.254,192.168.1.254
dhcp-option=eth0,249,172.17.19.0/24,192.168.1.252,172.17.19.0/24,192.168.1.252

This configuration is still present in the dnsmasq config file but this option is not sent anymore when i renew my dhcp lease
Does anyone know how to configure pihole v6 in order to send network route via dhcp-option ?

Thanks

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or if you run your Pi-hole as a Docker container:

docker exec -it <pihole-container-name-or-id> pihole -d

where you substitute <pihole-container-name-or-id> as required.

Your debug log shows your custom dhcp configuration to reside at /etc/dnsmasq.d/dnsmasq-wlan0.conf, but you haven't configured Pi-hole to include that directory:

-rw-r--r-- 1 pihole pihole 55K 11 mars  09:50 /etc/pihole/pihole.toml
   (…)
   [misc]
     (…)
     etc_dnsmasq_d = false
