Truffle Ropsten Running migration: 2_deploy_contracts.js fails with: TypeError: Cannot convert undefined or null to object

Question

Error encountered, bailing. Network state unknown. Review successful transaction s manually.

So I'd checked TxHash transactions manually, is here: https://ropsten.etherscan.io/tx/0x3b5415de9584f43aa6155843a64e453a49189e16fc83cf00e2323935c045f460

truffle(development)> migrate --network ropsten
Using network 'ropsten'.

Standardtoken has been deployed successfully despite the error but the process has been stopped and not complete deploy PatadiseToken.sol and ParadiseTokenSale.sol.

1_initial_migration.js , Works fine!

var Migrations = artifacts.require("./Migrations.sol");

module.exports = function(deployer) {
  deployer.deploy(Migrations);
};

2_deploy_contracts.js

module.exports = function(deployer, network, accounts) {
    // Use the accounts within your migrations.
    //console.log("Accounts: " + accounts);

    var userAddress = accounts[1];

    deployer.deploy(SafeMath);
    deployer.deploy(Ownable);
    deployer.link(Ownable, Pausable);
    deployer.deploy(Pausable);

    deployer.deploy(BasicToken);
    deployer.link(BasicToken, SafeMath);
    deployer.link(BasicToken, ERC20Basic);

    deployer.deploy(StandardToken);
    deployer.link(StandardToken, BasicToken);
    deployer.link(StandardToken, ERC20);

    deployer.deploy(ParadiseToken, userAddress);
    deployer.link(ParadiseToken, StandardToken);
    deployer.link(ParadiseToken, Ownable);
    deployer.link(ParadiseToken, SafeMath);

    var time = new Date().getTime() / 1000;

    var monkey = 1234;

    deployer.deploy(ParadiseToken, accounts[1]).then(function() {
        return deployer.deploy(ParadiseTokenSale, accounts[1], 10, 20, 1, time, 2, 15000, ParadiseToken.address);
    });

};

I think the problem is in 2_deploy_contracts.js

truffle.js is here:

var HDWalletProvider = require("truffle-hdwallet-provider");
var infura_apikey = "<My key is here> "; 
var mnemonic = "<My MetaMask Seed Phrases is Here>";

module.exports = {
  networks: {
    development: {
    provider: new HDWalletProvider(mnemonic, "http://127.0.0.1:8545/"),
      network_id: "*" // Match any network id
    },
    ropsten:  {
      provider: new HDWalletProvider(mnemonic, "https://ropsten.infura.io/" + infura_apikey),
      network_id: 3,
    }
  },
};

testrpc output:

I'm using mnemonic MetaMask Seed Phrases

Truffle compile works fine !

ParadiseToken.sol and ParadiseTokenSale.sol is here:

Could someone point out why is like that. Is here an obvious error. Did I miss something? Thank You, Robert.

Answer 1

I got exactly the same error. In my case, it turned out that I forgot to set a value which is passed to constructor of a contract.
