Error in creating instance of deployed contract using truffle console

Question

I deployed Token and Crowdsale contract in separate migration files. During Migration, there was no error. Migration logs are share:

Running migration: 2_deploy_token.js Deploying DappToken... ... 0xc1ed596e0249507186d75f2d42ba1c34e5b72697774baf9a283e0fb422214b70 DappToken: 0x949e24c24a79f437bbf75d3da7b9ba50235c2a8a Saving successful migration to network... ... 0x1c8bc4b87bfbfa40bb16aa3eb6cf0341efc79f444b1e293abd1f0db394881d55 Saving artifacts...

After this, when I tried to create an instance of Crowdsale using truffle console as

truffle(ganache)> DappTokenCrowdsale.deployed().then(ic => tokensale = ic)

I got the error:

Error: DappTokenCrowdsale has not been deployed to detected network (network/artifact mismatch)

Although i have successfully created the instance of DappToken contract. Related files are shared below:

DappTokenCrowdsale.sol

pragma solidity 0.4.24;

import "openzeppelin-solidity/contracts/crowdsale/Crowdsale.sol";

contract DappTokenCrowdsale is Crowdsale {

  constructor(
    uint256 _rate,
    address _wallet,
    ERC20 _token
  )
    Crowdsale(_rate, _wallet, _token)
    public
  {
  }
}

3_deploy_crowdsale.js

const DappToken = artifacts.require("./DappToken.sol");
const DappTokenCrowdsale = artifacts.require('DappTokenCrowdsale');

module.exports = async function(deployer, network, accounts) {
    const deployedToken = await DappToken.deployed();
    const _rate = 1000;
    const _wallet = accounts[1];
    const _token = deployedToken.address;

    await deployer.deploy(DappTokenCrowdsale, _rate, _wallet, _token);
};

2_deploy_token.js

const DappToken = artifacts.require("./DappToken.sol");

module.exports = async function(deployer, network, accounts) {
  const _name = "Dapp Token";
  const _symbol = "DAPP";
  const _decimals = 18;

  await deployer.deploy(DappToken, _name, _symbol, _decimals);
};

In case of migration you can't know for sure that the contract deployed, it returns transaction hash. You need to remove async/await(it is the simplest way) in order to see deployment result.

const DappToken = artifacts.require("./DappToken.sol");

module.exports = function(deployer, network, accounts) {
    const _name = "Dapp Token";
    const _symbol = "DAPP";
    const _decimals = 18;

    deployer.deploy(DappToken, _name, _symbol, _decimals)
        .then(function () {
             return deployer.deploy(Crowdsale, DappToken.address);
        });
};
