UnhandledPromiseRejectionWarning Error The contract code couldn t be stored please check your gas limit

0 votes

I am trying to deploy my simple solidity smart contract onto the Rinkeby Network but I keep getting the error:

UnhandledPromiseRejectionWarning: Error: The contract code couldn't be stored, please check your gas limit.

My solidity code is simple

pragma solidity ^0.4.18; 

contract Greetings{ 
  string public message; 

  function Greetings(string initialMessage) public{ 
    message = initialMessage;

  function setMessage(string newMessage) public {
    message = newMessage;

and my deploy script is:

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

const provider = new HDWalletProvider(  
  'twelve word mnemonic...', 

const web3 = new Web3(provider);

const deploy = async () => {
    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:['Hello World']})      
      .send({from: accounts[0], gas:'1000000'});                              

    console.log('Contract deployed to', result.options.address);

Had exactly same problem! Seems it is caused by the bug in the "truffle-hdwallet-provider" version 0.0.5. 

If you do the following should be okay, it worked for me.

npm uninstall truffle-hdwallet-provider
npm install --save truffle-hdwallet-provider@0.0.3

Then I ran the same contract which has deployed successfully.

This issue can be solved by adding the '0x' as the prefix of the bytecode:

.deploy({ data: '0x' + bytecode, arguments: ['Hi there!'] })

I believe bytecode is being treated as a single number rather than a series of bytes. Instead of submitting data:bytecode, try:

data:'0x0' + bytecode

it will "preserve" bytecode value as a string
