RangeError: Invalid string length

[kadishmal]

Perhaps for some reason ES sends an empty response which results in the following error.

 RangeError: Invalid string length
     at IncomingMessage.<anonymous> (/home/user/indexer-1.0.0/node_modules/elasticsearch/src/lib/connectors/http.js:171:34)
     at emitOne (events.js:77:13)
     at IncomingMessage.emit (events.js:169:7)
     at readableAddChunk (_stream_readable.js:146:16)
     at IncomingMessage.Readable.push (_stream_readable.js:110:10)
     at HTTPParser.parserOnBody (_http_common.js:109:22)
     at Socket.socketOnData (_http_client.js:311:20)
     at emitOne (events.js:77:13)
     at Socket.emit (events.js:169:7)

     at Socket.Readable.push (_stream_readable.js:110:10)
     at TCP.onread (net.js:523:20)

It happens in the following code:

request = this.hand.request(reqParams, function (_incoming) {
    ...
    incoming.on('data', function (d) {
==>       response += d;
    });
    ...

This happens with Node v5.0.0 and elasticsearch module v10.0.1.

It seems to be related to the Out Of Memory issue when creating a string out of the large ES response. The solution was to decrease the number of hits to return by ES on scan.
