Docker php 8 nginx configuration

I tried add PHP 8 to my docker project but can’t run it. My error maybe in nginx config file.

File docker-compose.yml:

version: "3.7"

services:
  phpfpm:

  }

  server {

    index index.php index.html;
    root /var/www/html;

    location / {
      try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
      try_files $uri =404;
      fastcgi_split_path_info ^(.+.php)(/.+)$;
      fastcgi_pass phpfpm:9000;
      fastcgi_index index.php;
      include fastcgi_params;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_param PATH_INFO $fastcgi_path_info;
    }
  }
}

In my case grafana and clickhouse works. But phpfpm doesn’t works. How I can fix nginx config in this case? Maybe also I must use upstream for phpfpm in this case?
