500 nginx error pages

Question

500 nginx error pages

In recent days I have been trying to get 500 pages to work, at first I used the exact same thing I used with 404 error but it didn't work and I think it is because it is a .php file

error_page 404 /errors/404.php;
error_page 500 502 503 504 /errors/500.php;

Is there a way to use a php file as a 500 error or do I need to create a "500.html" and copy all the code that looks like a page to the website?

To create a 500 error, I used:

fastcgi_pass unix:/var/run/php-fpm/php-fpm.soc;
instead of fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;

With 500.html there is an error, but with .php it is not, it is logical because I change the config to run php files, but in php errors it doesn't work either.

domain.com.conf:

server {
    listen       80;
    server_name  www.domain.com;

    root   /var/www/domain.com/www;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri.html $uri/ @extensionless-php;
    }

    location @extensionless-php {
        rewrite ^(.*)$ $1.php last;
    }

    error_page 404 /errors/404.php;
    error_page 500 502 503 504 /errors/500.php;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

500.php:

<!DOCTYPE html>
<html>
        <head>
                <?php include_once '../meta.php'; ?>
                <?=meta500?>
                <?php include_once '../header.php'; ?>
                <title><?=title500?></title>
        </head>
        <body>
                <?php include_once("../analyticstracking.php") ?>
                <?php include_once '../nav.php'; ?>
                <?php include_once 'containerError500.php'; ?>
        </body>
</html>
