Yes, I tried both `--add-module=testcookie-nginx-module --add-module=lua-nginx-module` and `--add-module=lua-nginx-module --add-module=testcookie-nginx-module`

> @tokumeo have you tried to use pre-built packages of nginx with Lua from openresty.org? No, I haven't tried that

I've managed to work around this problem using `map` directive for now, but I'm still curious why I can't get testcookie_ok variable using log_by_lua_block
