Node Driver crashes on multi get

When you try to execute this code the application crashes:

var async = require("async");
var couchBase = require("couchbase");

var json = {
"id1":

{ "id": "id1", "name": "Name 1" }

,

"id2":

{ "id": "id2", "name": "Name 2" }

};

var config =

{ "host": "localhost", "port": 8091, "username": "Administrator", "password": "password", "bucket": "requests" }

;

couchBase.connect(config, function(err, bucket) {
if (err)

{ console.log("Unable to connect to Couchbase bucket [" + config.bucket + "]", err); process.exit(1); }

console.log("Connected to Couchbase");

var ids = [];
var jsonDocs = [];
for (var key in json) {
if (json.hasOwnProperty(key))

{ var jsonDoc = json[key]; var id = jsonDoc.id; jsonDocs.push(jsonDoc); ids.push(id); }

}

bucket.get(ids, null, function(err, docs, metas) {
if (err) {
for (var j = 0; j < err.length; j++) {
if (err[j].code != 13) {
console.log(

{ err: err }

, "Unable to get existing entries using multiple get. Error in element [" + j + "]");
process.exit(1);
}
}
}
console.log("Checked all docs for existance");

async.map(jsonDocs, function(doc, callback) {
bucket.set(doc.id, doc, {}, function(err)

{ callback(err); }

);
}, function(err, results) {
if (err)

{ console.log("Unable to save all entries", err); process.exit(1); }

console.log("Saved all entries");
process.exit(0);
});
});
});
