In this course while deploying the first contract on rinkby network.It's not working for me as it throws an error Error: transaction underpriced
Below is the code which I tried to deploy
File: deploy.js
const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3');
const {interface, bytecode} = require('./compile');
const provider = new HDWalletProvider(
'melody fee rough pond kit insane trumpet section jewel stable deal make',
'https://rinkeby.infura.io/v3/1d4b424061734af684e16f68ab928c88',);
const web3 = new Web3(provider);
const deploy = async() => {
const accouts = await web3.eth.getAccounts();
console.log('Attempting to deploy from account', accouts[0]);
const result = await new web3.eth.Contract(JSON.parse(interface))
.deploy({data: bytecode, arguments: ['Hi there!']})
.send({gas: '1000000', from: accouts[0]});
console.log('Contract deployed to', result.options.address);
};
deploy();
Following is the error which I got:
Attempting to deploy from account 0x2d284659C5022543B7a4eFfC19015Bd92adeB845
Error: transaction underpriced
at C:\Users\91960\inbox\node_modules\web3-provider-engine\subproviders\web3.js:15:44
at XMLHttpRequest.request.onreadystatechange
What is the required value of gas parameter for deploying the contract?
UPDATE
I updated the required line of code : .send({gas: '2000000000', from: accouts[0]});
This is the error I got:
`
