KeyError: 'security_experimental_enabled' when updating Yunohost setting in webadmin

[SohKa]

Describe the bug

In the Yunohost webadmin, under "Tools > YunoHost settings > Other", when I try to change setting IP versions to consider for DNS configuration and diagnosis from Both to IPv4 only, I get a 500 Unexpected server error.

Via CLI, it works as expected.

Context

• Hardware: Raspberry Pi at home
• YunoHost version: 12.0.6 (stable)
• I have access to my server: Through SSH | through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: yes
  • If yes, please explain: probably not related, but I set up a Tailscale client, a L2TP tunnel and I changed the DNS name servers in /etc/resolv.dnsmasq.conf for the NextDNS ones. Also I've enable the setting Experimental security features a few weeks ago, and I disabled it a few days ago (I don't rememeber if it was via webadmin or CLI)

To reproduce

• Webadmin

  1. Go to Yunohost webadmin, under "Tools > YunoHost settings > Other"
  2. Change setting IP versions to consider for DNS configuration and diagnosis to another value
  3. Click on Save
  4. See error message

• CLI Here it works as expected:

  
  myuser@myserver:~ $ sudo yunohost settings set misc.network.dns_exposure -v ipv4

Info: Saving the new configuration... Success! Config updated as expected

### Logs

No logs in "Tools > Logs", so I must paste the stacktrace here, sorry.

Hum, I can't reproduce this error, but there's indeed a visible prop on a section in the misc tab:

[misc.tls_passthrough]
visible = "security_experimental_enabled"

        [misc.tls_passthrough.tls_passthrough_enabled]
        type = "boolean"
        default = false

        [misc.tls_passthrough.tls_passthrough_explain]
        type = "alert"
        style = "info"
        icon = "info"
        visible = "tls_passthrough_enabled"

        [misc.tls_passthrough.tls_passthrough_list]
        type = "tags"
        # Regex is just <domain regex>;<destination>;<port>
        pattern.regexp = '^(([^\W_A-Z]+([-]*[^\W_A-Z]+)*\.)+((xn--)?[^\W_]{2,}));(([^\W_A-Z]+([-]*[^\W_A-Z]+)*\.)+((xn--)?([^\W_]{2,}|[0-9]{1,3})));[0-9]{1,}$'
        pattern.error = "You should specify a list of items formatted as DOMAIN;DESTINATION;DESTPORT, such as yolo.test;192.168.1.42;443"
        default = ""
        visible = "tls_passthrough_enabled"

We chose to not pass other panel's settings in context so this is expected to not work. Should we move this section to the security tab?
