v2.10.0-beta.1: Caddy panics when using ECH's DNS sub-option #6885

{
ech ech.triplebit.net {
dns cloudflare {env.CF_ECH_API_TOKEN}
}
}

This also happens when I specify the API key in the file, so the fact I'm using an environment variable is not relevant.
Just for the sake of completeness, the regular way to configure this does work fine for me:
{
dns cloudflare {env.CF_ECH_API_TOKEN}
ech ech.triplebit.net
}
