$bytes_received variable not working

[junly]

My nginx is compiled and installed, and the version installed is
       Nginx version: nginx / 1.14.0

The parameters for compilation are:
      Configure the arguments:--prefix=/etc/nginx
--sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules
--conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log-

nginx log format：
        log_format main'[$time_iso8601] $remote_addr - $remote_user "$scheme
$host $request $cookie_group_id" $status $body_bytes_sent "$http_referer"
"$bytes_received" "$http_user_agent" "$http_x_forwarded_for"';

When I use nginx -t detection configure file, nginx emerg is prompted with
unknown bytes_received variable

I now want to use the bytes_received variable, how do I fix it?
