Question

Hi I am trying to deploy a contract but keep getting this error. I am new to solidity.

I am running the cmd node deploy.js

error message

const interface = JSON.parse(compile).contracts["lottery.sol"].Lottery.abi; ^ SyntaxError: Unexpected token o in JSON at position 1 at JSON.parse () at Object.

Deploy.js

const HDWalletProvider = require('@truffle/hdwallet-provider');
const Web3 = require('web3');
const compile = require('./compile');
const interface = JSON.parse(compile).contracts["lottery.sol"].Lottery.abi;
const bytecode = JSON.parse(compile).contracts["Inbox.sol"].Lottery.evm.bytecode.object;


const provider = new HDWalletProvider(
    '<mnemonic phrases>',
    'https://rinkeby.infura.io/v3/<xxxxxxxxx>'
);

const web3 = new Web3(provider);

const deploy = async () => {
    const accounts = await web3.eth.getAccounts();

    console.log('Attempting to deploy from accounts', accounts[0]);

    const result = await new web3.eth.Contract(interface)
        .deploy({data: '0x' + bytecode})
        .send({from: accounts[0]});
    
    console.log(interface);
    console.log('Contract deployed to', results.options.address);
};

compile.js

const path = require('path');
const fs = require('fs');
const solc = require('solc');

const lotteryPath = path.resolve(__dirname, 'contracts', 'lottery.sol');
const source = fs.readFileSync(lotteryPath, 'UTF-8');

var input = {
    language: 'Solidity',
    sources: {
        'lottery.sol' : {
            content: source
        }
    },
    settings: {
        outputSelection: {
            '*': {
                '*': [ '*' ]
            }
        }
    }
}; 

module.exports = JSON.parse(solc.compile(JSON.stringify(input)));

Answer 1

This part is suspicious. ["Inbox.sol"].Lottery

You read Inbox.sol, why do I access "Lottery" instead of "Inbox"?
