provision http.handlers.waf: invalid WAF config from string: failed to readfile: invalid argument

[JKSTAFF]

Pretty much the same issue like #58 , but happend on latest caddy(both bin and docker) with coraza-caddy/v2.

Build parameter

xcaddy build --with github.com/corazawaf/coraza-caddy/v2

Dockerfile

FROM caddy:builder AS builder
RUN xcaddy build \
    --with github.com/corazawaf/coraza-caddy/v2
FROM caddy:latest
COPY --from=builder /usr/bin/caddy /usr/bin/caddy

Caddyfile

{
    order coraza_waf first
    https_port 443

    admin off
    acme_dns cloudflare MY_API_KEY
}
*.mydomain.com {
    coraza_waf {
        load_owasp_crs
        directives `
            Include etc/caddy/rules/@coraza.conf-recommended
            Include /etc/caddy/rules/@crs-setup.conf.example
            Include /etc/caddy/rules/@owasp_crs/*.conf
        SecRuleEngine On
        `
    }
    @sub host sub.mydomain.com
    handle @hub {
        ## webport
        reverse_proxy 127.0.0.1:8080
    }
}

        Include @coraza.conf-recommended
        Include @crs-setup.conf.example
        Include @owasp_crs/*.conf

Avoid using @ names as it is reserved for the local filesystem unless you want the default config files.
Coraza ships OWASP CRS by default
