load error via timeout if is JSON is invalid.

[valentinedwv]

If there is not an endline after the last closing brace, a raw json will timeout on read and will not load

Loading ecrr from a github, initially thought this was a issue with the above, but it may be a github loading rate issue. since it timesout after 8-10 files

Think that if a file is invalid, it causes a load error, because the file goes to headless
