This package assumes request.files.progressive to be present in the json, but progressive seems to be removed now, causing code 4 errors.
example:
https://player.vimeo.com/video/783455878/config
request.files.hls.cdns is still present but the current logic doesn't check for it because it already threw the error. The code may need to be structured a little bit differently so when it doesn't find progressive it then checks for cdns.
