How do I get the public file URI for a media file from jsonapi?
Here's the correct path:
http://mysite.com/jsonapi/node/MY_CONTENT_TYPE?include=field_ref_media_audio.field_media_audio_file&amp;fields[file--file]=uri,url

This results in a value for uri such as:
&quot;value&quot;: &quot;public:/sites/default/files/coolstuff/audio/apples-bananas-pears.mp3&quot;,
