Nginx doesn't pass response headers of NodeJS Server - nginx

Question

I have trouble configuring my nginx reverse proxy. As it stands the requests look like this:
root#devserver:~# curl -I https://example.com
HTTP/2 401
server: nginx
date: Fri, 15 Oct 2021 11:42:00 GMT
content-type: text/html; charset=utf-8
content-length: 172
www-authenticate: Basic realm="please login"
x-xss-protection: 1; mode=block
x-content-type-options: nosniff
referrer-policy: no-referrer-when-downgrade
content-security-policy: default-src 'self' http: https: data: blob: 'unsafe-inline'; frame-ancestors 'self';
permissions-policy: interest-cohort=()
strict-transport-security: max-age=31536000; includeSubDomains
root#devserver:~# curl -I http://127.0.0.1:5000
HTTP/1.1 500 Internal Server Error
X-Powered-By: Express
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS
Access-Control-Allow-Headers: *
Content-Security-Policy: default-src 'none'
X-Content-Type-Options: nosniff
Content-Type: text/html; charset=utf-8
Content-Length: 1386
Date: Fri, 15 Oct 2021 11:42:52 GMT
Connection: keep-alive
Keep-Alive: timeout=5
The Access-Control headers are missing, and I cannot figure out how I can configure nginx to pass them to the browser.
My nginx configuration looks currently something like this:
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.com;
root /var/www/example.com;
# SSL
...
# reverse proxy
location / {
proxy_pass http://127.0.0.1:5000;
proxy_http_version 1.1;
proxy_cache_bypass $http_upgrade;
# Proxy headers
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Forwarded $proxy_add_forwarded;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Port $server_port;
# Proxy timeouts
proxy_connect_timeout 60s;
proxy_send_timeout 60s;
proxy_read_timeout 60s;
}
}
Thanks for the help in advance :)

location / {
proxy_pass https://127.0.0.1:80;
proxy_set_header Host $host;
proxy_hide_header X-Frame-Options;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Accept-Encoding "";
client_body_timeout 3000;
fastcgi_read_timeout 3000;
client_max_body_size 128m;
