Correct moving locations in default Nginx to separate files

Hello

I have a lot of location routings inside my default Nginx default file. I decided to move some of them based on the application that use them in separate .conf files. The problem is that when I transfer locations to the separate files and include them info the default files nginx does not restart

Main file :

server {
    # Enable HTTP/2
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name xxxx www.xxx;


    ssl_certificate /etc/xxxx;
    ssl_certificate_key /etc/xxx;

    # Include the SSL configuration from cipherli.st
    include snippets/ssl-params.conf;
    

    include /etc/nginx/conf.d/*.conf;

	
    location / {
				xxxx
        proxy_pass http://localhost:5000/;
				xxxx
    }
}

The sample.conf file

location /test/ {       
		xxxx
      proxy_pass http://localhost:7000/

    }

    location /test2/ {
      proxy_pass http://localhost:8000/;
    }
    

    location /sam/test3 {
      return 301 /sam/test2/;
    }
