I was trying to connect to my node via IPC using web3_ipc. But i got hit by:

 You tried to send "eth_getBalance" synchronously. Synchronous requests are not supported by the IPC provider.

My code is as:

var web3_extended = require('web3_ipc');
var path = require('path');
var absolutePath =  path.relative('./','/home/pr.singh/.ethereum/geth.ipc');
var options = {
  host : absolutePath,
  // host: 'http://10.10.23.139:8013',
  ipc : true,
  personal: true, 
  admin: true,
  debug: false
};

var web3 = web3_extended.create(options);

exports.checkBalance = function(req, res) {
    var bal = req.body.balance;
                var accountBalance=web3.eth.getBalance(bal).toNumber(); 
                console.log(accountBalance);
}

If I connect using rpc, everything works good but while connecting via IPC , I am getting error. Any help?
