I have new information about this problem...
With a little modification on NodeJs code I got this error:
Modification:
app.get('/have_pswd', function (req, res) {
var serv_req = new My_controller.Void();
controller_svc.HavePassword(serv_req, function(error, serv_res) {
if (error !== null) throw error;
res.json(serv_res);
});
});
Error:
RangeError: offset is not uint

Somebody have an idea about it?
