[] serialize, then parse, but not get [], is {}, why?

test.proto:
message test{
repeated int32 history = 1;
}

---

my nodejs code:
var Schema = require('protobuf').Schema;
var schema = new Schema(fs.readFileSync(test.desc'));
var req_ob = {
hisatory: []
};
var Req = schema['test'];
var s = Req.serialize(req_ob);
console.log("request:" + JSON.stringify(req_ob));

var Res = schema['test'];
var r = Req.parse(s);

console.log("response:" + JSON.stringify(r));

console:
request:{"hisatory":[]}
response:{}

why response is {}, not {"hisatory":[]} ???

That's the wrong protobuf module. Should be closed.
