How to redirect directories in nginx?

Question

MODX

Raised the site on nginx, but the 301st redirect from the folder does not work.
Those. the path example.com/folder/ works, but
without the slash example.com/folder gives a 403 error even though the directory is in place and open for reading.

server {
    listen      <server-ip>:443;
    server_name www.example.com;

    ssl         on;
    ssl_certificate      /home/user/conf/web/ssl.example.com.pem;
    ssl_certificate_key  /home/user/conf/web/ssl.example.com.key;

    return 301 https://example.com$request_uri;
}
server {
    listen      <server-ip>:443;
    server_name example.com;
    root        /home/user/web/example.com/public_html;
    index       index.php index.html;
    access_log  /var/log/nginx/domains/example.com.log combined;
    access_log  /var/log/nginx/domains/example.com.bytes bytes;
    error_log   /var/log/nginx/domains/example.com.error.log error;

    ssl         on;
    ssl_certificate      /home/user/conf/web/ssl.example.com.pem;
    ssl_certificate_key  /home/user/conf/web/ssl.example.com.key;

    location / {

        if (!-e $request_filename) {
            rewrite ^/(.*)$ /index.php?q=$1 last;
        }

        location ~* ^.+\.(jpeg|jpg|png|gif|bmp|ico|svg|css|js)$ {
            expires     1M;
        }

        location ~ [^/]\.php(/|$) {
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            if (!-f $document_root$fastcgi_script_name) {
                return  404;
            }

            fastcgi_pass    127.0.0.1:9001;
            fastcgi_index   index.php;
            include         /etc/nginx/fastcgi_params;
        }
    }

    error_page  403 /error/403.html;
    error_page  404 /error/404.html;
    error_page  500 502 503 504 /error/50x.html;

    location /error/ {
        alias   /home/user/web/example.com/document_errors/;
    }

    location ~* "/\.(htaccess|htpasswd)$" {
        deny    all;
        return  404;
    }

    include     /etc/nginx/conf.d/phpmyadmin.inc*;
    include     /etc/nginx/conf.d/phppgadmin.inc*;
    include     /etc/nginx/conf.d/webmail.inc*;

    include     /home/user/conf/web/snginx.example.com.conf*;
}

if (!-e $request_filename) {
rewrite ^/(.*)$ /index.php?q=$1 last;
}
Breaks the default behavior of nginx on this topic. From the point of view of if -e folder does not exist, only folder/ exists, so the request goes to php.
