Basic config issue at caddy startup

[cocochepeau]

Hi. Here is my default config:

(cache) {
        cache {
                redis {
                        url 127.0.0.1:6379
                }
        }
}

*.up2share.site {
        import securityheaders
        import tlsconfig
        import logconfig
        import cache

        root * /mnt/data/www/up2share/prod/public

        handle {
                try_files {path} /index.php
                php_fastcgi unix//run/php/php8.1-fpm.u2s.sock
        }

        encode zstd gzip
}

And here is how I built caddy binary:

xcaddy build \
    --with github.com/caddy-dns/cloudflare \
    --with github.com/WeidiDeng/caddy-cloudflare-ip \
    --with github.com/caddyserver/cache-handler \
    --with github.com/darkweak/storages/redis/caddy

Caddy validates the Caddyfile properly. But this is what I get when starting caddy.service:

Jan 05 16:28:25 tl-02 caddy[1776325]: {"level":"info","ts":1736094505.8401146,"logger":"http.handlers.cache","msg":"Set backend timeout to 10s"}

Caddy version:
