proxy_pass priority and location - nginx

Question

I am trying to proxy all incoming requests from nginx to NodeJS, excluding uri "/cabinet/...". So according to official nginx documentation, it's work perfectly when I am trying to proceed file on same server, but when I am trying proxy to node server, whole request are forced to node (including /cabinet/)
So what I am doing wrong?
server {
listen 80;
listen 443 ssl http2;
server_name mysite.dev;
root "/home/vagrant/code/cabinet/public";
index index.html index.htm index.php;
charset utf-8;
location / {
proxy_pass http://localhost:5000;
#try_files $uri $uri/ /index.html;
}
location /cabinet/ {
#try_files $uri $uri/ /index.php?$query_string;
try_files $uri $uri/ /index2.html;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_index index.php;
