nginx reverse proxy 302 custom handler not working

Question

location / {
    fastcgi_intercept_errors on;
    proxy_pass https://drive.google.com/uc?$query_string;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host drive.google.com;
    proxy_set_header Referer https://drive.google.com;
    error_page 301 302 307 = @handle_redirects;

}
location @handle_redirects {
    set $redirect_location '$upstream_http_location';
    proxy_pass $redirect_location;
    proxy_cache ngx-cache;
    proxy_cache_key $query_string;
    proxy_set_header X-Real-IP $remote_addr;

I believe you need to add:

  proxy_intercept_errors on;

Stolen from Intercepting backend 301/302 redirects (proxy_pass) and rewriting to another location block possible?

I had a similar issue while trying to proxy the images from https://picsum.photos website. They return a 302 redirect to a HMAC-signed URL when requesting a particular picture.

The working solution for me is:

server {
    listen 80;
    server_name dog.localhost.direct;
    location / {
        proxy_ssl_server_name on;
        proxy_intercept_errors on;
        error_page 301 302 307 = @handle_redirect;
        proxy_pass https://picsum.photos/id/237/536/354;
    }
    location @handle_redirect {
        set $saved_redirect_location '$upstream_http_location';
        resolver 8.8.8.8;
        proxy_pass $saved_redirect_location;
    }
}

Hope this will help somebody.
