<h3 id="overview">Overview</h3>
<p>To reproduce:</p>
<p>1. Add media field to any bundle (e.g. article), and pick >=1 media type, but make one of them use the "File" MediaSource (in Standard: the "Document" media type)<br>
2. Create a template for an article<br>
3. Add the Card SDC or all-props SDC (I think it has to be a component with an image prop or something that media to be linked to)<br>
4. Select the component<br>
5. 500 error in component instance form</p>
