openresty proxy_pass rewrite not with potree view

I have openresty and node application openresty used to authenticate user using lua. here is my nginx.conf file.
When give location /potree app loading properly but when click on folders in its not opening
But when I use location / its working file. attached image for reference.

Here is nginx.conf file

`server {
listen 80 default_server;
listen 80;
listen [::]:80;
server_name localhost;
resolver 127.0.0.11 valid=1s;
set $session_check_ssi off;
access_by_lua '
local opts = {
My keycloak config
}
-- call introspect for OAuth 2.0 Bearer Access Token validation
local res, err = require("resty.openidc").authenticate(opts)
';

I disabled caching so the browser won't cache the site.
expires 0;
add_header Cache-Control private;

location /potree {
rewrite ^/potree(.*) /$1 break;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://potree:1234;
}
error_page 404 /404.html;
location = /40x.html {
}
redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}`

Start with the nginx.conf shown in the issue, especially the /potree location, rewrite, and proxy_pass settings. Compare the browser requests and folder-navigation behavior under /potree with the working root location, then verify that Potree folder clicks load successfully through the proxied path.
