Nginx rewrites for using production uploads in development

As a follow up on this topic, I’m trying to use production (or external) media uploads in my development environment.

A symlink uploads folder is not working and a synced uploads folder to an external wouldn’t work either in a shared code base.

So I’m back at making it work with a nginx child template.
I found this snippet that uses the production media url if the local media url is not found:

{% extends 'roles/wordpress-setup/templates/wordpress-site.conf.j2' %}

{% block location_primary -%}
location / {
  try_files $uri $uri/ /index.php?$args;
}

location ~ "^(.*)/app/uploads/(.*)$" {
  try_files $uri @production;
}

location @production {
  rewrite "^(.*)/app/uploads/(.*)$" "https://example.com/app/uploads/$2" redirect;
}
{% endblock %}

I used it in other projects that had a flat uploads folder (not monthly & yearly organized) and that worked perfectly!

So I’m trying to make this work with a monthly & yearly organized folder structure:

{% extends 'roles/wordpress-setup/templates/wordpress-site.conf.j2' %}

{% block location_primary -%}
location ~ "^(.*)/app/uploads/(.*)$" {
  try_files $uri $uri/ @production;
}

location @production {
  rewrite "^(.*)/app/uploads/([0-9]+/[0-9]+/)?(.*)$" "https://example.com/app/uploads/$2$3" redirect;
}

location / {
  try_files $uri $uri/ /index.php?$args;
}
{% endblock %}

But this is not working yet unfortunately…
I keep getting 404 Not Found for every upload, it’s not redirecting to the production url.

Any ideas?
