Would be nice if I could actually see the JSON that it's choking on. Would be nice if there was a debug or verbose flag for that.

BTW - In my case the error was caused by the CSRF protection in Django as explained here, but it would have been easier to determine the problem if I could see the HTML that get-graphql-schema was attempting to parse as JSON.
