How to set up a log in ngnix + nodejs, where to write something for the http request log?

Question

Node.js

upstream app_node {
  ip_hash;
  server server_local1 weight=10;
        server server_local2 weight=20;
        server server_local3 weight=50;
}

server {
   listen 80 default_server;
   ...
   access_log  /var/log/nginx/app.access.log main;
   error_log   /var/log/nginx/app.error.log notice;
   rewrite_log on;

   fastcgi_buffers 256 16k;
   fastcgi_buffer_size 32k;

   location /rest {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_pass http://app_node;
    proxy_redirect off;
  }
       ...
      # дальше идут настройки php
}

When requests go to php, everything is logged, when the log is empty on the url node.
How to fix it ?
UPD
rewrite_log on;
if you remove the idea, there should be logs for all requests (did not check),
but since pm2 writes logs of everything that is displayed through console.log, I made a log in the application and that's enough for me.
