Comment (by azaozz):

 Been looking at this (on and off) for the past few weeks. Unfortunately
 still can't reproduce it consistently (apart from uploading made-up 200MB
 images that always cause a timeout).

 > Many users are experiencing a "The response is not a valid JSON
 response" error when uploading images, usually caused by a timeout on the
 server.

 Wondering if we can add better error message there. As far as I see "not a
 valid JSON response" is most often caused by extra content like PHP notice
 appended to the JSON, HTTP 404, 403 or 500 error, and by a server timeout
 (connection closed). Knowing the exact cause would help to resolve this a
 lot, and also be a great addition to Site Health for WP 5.2.
