Use sql file in seeder
1) Clear sql file from unnecessary lines and leave only 
insert
query For example: 
INSERT INTO `topwords` (`id`, `word`, `frequency`, `deleted`) VALUES
(1, 'the', 22038615, 0),
(2, 'be', 12545825, 0)
...
2) Add SQL file in a public folder or App/someFolderForSQLFiles 3) Use this in seeder 
  $path = base_path('public\topwords.sql');
        $sql = file_get_contents($path);
        DB::unprepared($sql);
Or this: 
 $path = 'app/someFolderForSQLFiles/topwords.sql';
 DB::unprepared(file_get_contents($path));

increase buffer size
The following issue:
...upstream sent too big header while reading response header from upstream...
Is fixed by adding these lines:
fastcgi_buffers 8 16k; # increase the buffer size for PHP-FTP
fastcgi_buffer_size 32k; # increase the buffer size for PHP-FTP
fastcgi_connect_timeout 60;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
To the site's configuration file:
server {
    listen 80;
    server_name pm.use.ge;
    root /var/www/pm.use.ge/public_html;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

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

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;

        include fastcgi_params;                                                                                                                                >        deny all;
    }
}
So that the final configuration file looks like this:
server {
    listen 80;
    server_name pm.use.ge;
    root /var/www/pm.use.ge/public_html;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

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

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;

        fastcgi_buffers 8 16k; # increase the buffer size for PHP-FTP
        fastcgi_buffer_size 32k; # increase the buffer size for PHP-FTP
        fastcgi_connect_timeout 60;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;

        include fastcgi_params;                                                                                                                                >        deny all;
    }

is_callable vs method_exists
method_exists() does not care about the existence of 
__call()
, whereas 
is_callable()
does: 
<?php
class Test {
  public function explicit(  ) {
      // ...
  }
  
  public function __call( $meth, $args ) {
      // ...
  }
}

$Tester = new Test();

var_export(method_exists($Tester, 'anything')); // false
var_export(is_callable(array($Tester, 'anything'))); // true
?>
