Nginx append a trailing slash to the url - django

Question

I am having an issue in Safari and IE where a django redirect does not include the authorization headers. This leads to the requests being rejected.
These redirects happen with the URL does not end with a /.
So I am trying to handle adding the / in the nginx config before it is passed to the app.
Here is my nginx config:
server {
server_name ~^((stage|prod)-)?chalktalk-react-40.*;
listen 28000 default_server;
location ~ ^/static/(?P<file>.*) {
root /chalktalk/var/chalktalk-react-40;
add_header 'Access-Control-Allow-Origin' $cors_origin;
# Inform downstream caches to take certain headers into account when reading/writing to cache.
add_header 'Vary' 'Accept-Encoding,Origin';
try_files /staticfiles/$file =404;
}
location ~ ^/media/(?P<file>.*) {
root /chalktalk/var/chalktalk-react-40;
try_files /media/$file =404;
}
location / {
if ($request_uri ~ ^([^.\?]*[^/])$) {
return 301 $1/;
}
}
# API endpoints have their own authentication and authorization
# schemes, so we bypass basic auth.
location ~ ^/(api|admin|ws)/ {
try_files $uri #proxy_to_app;
}
rewrite ^(.*)/favicon.ico$ /static/pages/homepage/logo-nonname.png last;
location #proxy_to_app {
proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
proxy_set_header X-Forwarded-Port $http_x_forwarded_port;
proxy_set_header X-Forwarded-For $http_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_read_timeout 1200;
proxy_redirect off;
proxy_pass http://chalktalk-react-40_app_server;
}
# Forward to HTTPS if we're an HTTP request...
if ($http_x_forwarded_proto = "http") {
set $do_redirect "true";
}
# Run our actual redirect...
if ($do_redirect = "true") {
rewrite ^ https://$host$request_uri? permanent;
}
}
I know I have to add a rewrite and this is the rewrite I am trying to add:
server {
...
listen 28000 default_server;
rewrite ^([^.]*[^/])$ $1/ permanent;
...
}
The issue that I have with that is when I try to visit: example.com/admin, I get example.com:28000/admin/.
How do i make sure it leads to this example.com/admin/ without the port # inserted there?
UPDATE:
I updated the config to have the following:
server {
server_name ~^((stage|prod)-)?chalktalk-react-40.*;
listen 28000 default_server;
port_in_redirect off;
rewrite ^([^.]*[^/])$ $1/ permanent;
...
}
But I get this error in Safari:

Use either the port_in_redirect directive, for example:
port_in_redirect off;
Or tell Nginx exactly what you want in the rewrite directive, for example:
rewrite ^([^.]*[^/])$ $scheme://$host$1/ permanent;
