How do I get an octet-stream in Node.js using http (or request)? -

i'm writing node.js script parse wikidata database dumps , insert them own database. i'm having troubles downloading files, seems both node.js's http module , request module npm ending response stream early. i'm getting following error:

events.js:85       throw er; // unhandled 'error' event             ^ syntaxerror: unexpected end of input     @ parse (native)     @ emit (/var/app/current/node_modules/split/index.js:27:17)     @ next (/var/app/current/node_modules/split/index.js:48:7)     @ stream.<anonymous> (/var/app/current/node_modules/split/index.js:53:5)     @ stream.stream.write (/var/app/current/node_modules/split/node_modules/through/index.js:26:11)     @ gunzip.ondata (_stream_readable.js:540:20)     @ gunzip.emit (events.js:107:17)     @ readableaddchunk (_stream_readable.js:163:16)     @ gunzip.readable.push (_stream_readable.js:126:10)     @ gunzip.transform.push (_stream_transform.js:140:32) 

i'm using following code download database dump:

var streamer = request.get("http:/dumps.wikimedia.org/other/wikidata/20150330.json.gz").pipe(require('zlib').creategunzip()).pipe(split(json.parse));  streamer.on('data', function(obj){     ... }); 

the error same whether use request module or built-in http module.
