title: Why do I get 404 error when trying to GET image from heroku?
body: <p>So I have deployed my Django project via heroku. I'm testing my api calls, but getting error when fetching images.<br>
  On request, I was able to get this data :<br></p>
  <pre><code>{
      &quot;id&quot;: 1,
      &quot;source&quot;: 2,
      &quot;category&quot;: [
          1,
          4
      ],
      &quot;key_line&quot;: &quot;blabla&quot;,
      &quot;footnote&quot;: &quot;&quot;,
      &quot;created_at&quot;: &quot;2021-07-19&quot;,
      &quot;image&quot;: &quot;https://bookcake.herokuapp.com/api/cake/media/None/rlvdmseoghk.jpg&quot;,
  }
  </code></pre>
  <p>Now the problem is the <code>image</code> field. All other data show up fine in the front-end, but the image doesn't. As well, nothing shows up when I click on that link. What could be the problem? <br> <br> Here's my settings.py file for your information, but I don't see any problem with it.<br></p>
  <pre><code>...
  MEDIA_URL = 'media/'
  MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
  </code></pre>
