[Freeswitch-users] mod_v8 - still no File object?

I've been running old FS w/Spidermonkey, finally upgraded and testing in mod_v8. My javascript returned this: Exception: ReferenceError: File is not defined (near: "var fd = new File(myPath + myFileName") I read about the lack of XML and File back in 2015, but I assumed it has been included since spidermonkey no longer is an option. No? Other options?
