V2 : help to set up a Yourls instance

Thanks for your help, but I don’t understand what I’m supposed to do.

I tried this :

(yourls) {

    # Add trailing slash for directory requests
    @canonicalPath {
        file {
            try_files {path}/yourls-loader.php
        }
        not {
            path */
        }
    }
    redir @canonicalPath {path}/ 308

    # If the requested file does not exist, try index files
    try_files {path} {path}/index.php index.php

    # Proxy PHP files to the FastCGI responder
    @phpFiles {
        path *.php
    }
    reverse_proxy @phpFiles unix//run/php/php7.4-fpm-caddy.sock {
        transport fastcgi {
            split .php
        }
    }

    file_server 
    encode zstd gzip
    import logs
}

But is was exactly the same as with the try_files I tried earlier. The links were redirected, but the admin is not accessible. What should I do ?

I don’t want to go back to Caddy 1, but at least it worked perfectly there.
