I am trying to deploy my contract to rinkeby test network but unable to do so here is my contract code.

pragma solidity ^0.4.17;
contract Inbox {
    string public message;
    function Inbox(string initialMessage) public {
        message = initialMessage;
    function setMessage(string newMessage) public {
        message = newMessage;

and here is deploy.js code

const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3');
const { interface, bytecode }  = require('./compile');

const provider = new HDWalletProvider(
  'key pharase',

const web3 = new Web3(provider);

const deploy = async ()=> {
  const accounts = await web3.eth.getAccounts();
  console.log('Attempting to deploy from account ',accounts[0]);
  const result = await new web3.eth.Contract(JSON.parse(interface))
    .deploy({ data: bytecode, arguments: ['Hi there!'] })
    .send({gas: '7200000', from:accounts[0]});
  console.log('Contract Deployed to ',result.options.address);

I am getting this errror
