Nginx / Uwsgi cache configuration

Question

I have the following Nginx cache site.conf file:

uwsgi_cache_path /home/ubuntu/cache levels=1:2 keys_zone=one:10m;

server {
    listen 80;
    server_name genelizleyici.com;

    location /api/tweets/ {
        uwsgi_cache one;
        uwsgi_cache_valid any 1m;
        uwsgi_cache_key $request_uri;

        include uwsgi_params;
        uwsgi_pass unix:///home/ubuntu/uwsgi.socket;
    }

    location / {
        uwsgi_cache one;
        uwsgi_cache_valid any 1m;
        uwsgi_cache_key $request_uri;

        include uwsgi_params;
        uwsgi_pass unix:///home/ubuntu/uwsgi.socket;
    }

}

It is working fine for the /api/tweets/ and the json responses are cached but the home page, (i.e. '/') is not cached.

The cache configurations are equivalent. The only difference I can think of between these two is that, the responses of the first are json.

Any ideas why the cache configuration for / not taken into account? Thanks.
