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

The parameters for compilation are:

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?
