The directive lua_kong_load_var_index is implemented by nginx C module lua-kong-nginx-module,
and it is integrated with Kong.

You can try nginx -V to check if this module is enabled.

i user this command 'kong start -c /etc/kong/kong.conf --v'

return me this msg:
2022/08/12 15:18:46 [debug] found OpenResty 'nginx' executable at /usr/local/openresty/nginx/sbin/nginx

why not load /etc/kong/kong.conf

/etc/ is protected in MacOS. If you install things in homebrew then you must use the homebrew prefix, which is in /usr/local/opt/<your-app>.
