[knot-dns-users] kresd not starting with lua error

Hello, Running knot-resolver 5.6.0-1 amd64 (latest available via apt) on debian-12 bookworm, fully upgraded. systemctl start kresd@1 fails to run. systemctl status kresd@1 shows the following errors: [system] error while loading config: ...b/x86_64-linux-gnu/knot-resolver/kres_modules/policy.lua:378: bad argument #1 to 'create' (table expected, got nil) (workdir '/var/lib/knot-resolver') Here is my kresd.conf. It had been running ok for a long time ( I don't recall making any changes) : - Default empty Knot DNS Resolver configuration in -*- lua -*- -- Bind ports as privileged user (root) -- net = { '127.0.53.0' } -- Switch to unprivileged user -- user('knot-resolver','knot-resolver') -- Unprivileged -- cache.size = 100*MB policy.add(policy.suffix(policy.FLAGS({'NO_CACHE'}), internalDomains)) policy.add(policy.suffix(policy.STUB({'127.53.0.0'}), internalDomains)) policy.TLS_FORWARD({ -- multiple servers can be specified for a single slice -- the one with lowest round-trip time will be used {'9.9.9.9', hostname='dns.quad9.net'}, {'149.112.112.112', hostname='dns.quad9.net'}, }) All help is greatly appreciated, Mike Wright
