Fire App Builder will not render Closed Captions from a Valid CC URL - Been looking for help for over a year

Fire App Builder will not pull in .VTT files from a valid url We are required by law to provide closed captions for our videos. The @mCloseCaptionUrls value never populates from a valid url. Error: Value for mCloseCaptionUrls was null so not set for Content, this may be intentional.

Start with the DynamicParser recipe and the Content model mapping, then compare the srt entry with the XML's srt element and trace how mCloseCaptionUrls is populated. Done means the valid .vtt URL is retained for Content and closed captions render for the supplied video.
