title: File upload returns undefined HTTP status
body: <p>I have a Django / React application hosted in AKS. React's build is hosted statically with Nginx. The Nginx container is exposed through a ClusterIP, Ingress &amp; Nginx-Controller. The In this app, I'm doing a file upload, which returns nothing. Not an error, not an HTTP status code, nothing. That makes debugging very hard. This doesn't happen locally, and it only happens with files bigger than approx 10mb. Already increased the <code>client_max_body_size</code> in the <code>default.conf</code> of the nginx host. Can't find anything in the <a href="https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/" rel="nofollow noreferrer">Controller docs</a> that indicates a too large filesize, and this would also result in a HTTP 413. Anyone familiar with this?</p>
  <p>In React I simply use <code>axios</code> with <code>formData</code>:</p>
  <pre class="lang-js prettyprint-override"><code>let formData = new FormData();
  axios.post(`${API_SERVER}/builds`, formData).then(response =&gt; {
                  console.log(response);
              }).catch(error =&gt; console.log(error));
  </code></pre>
  <p>The HTTP response:</p>
  <pre><code>undefined undefined undefined
