Lesson 6 error: "Deployed contract: undefined" when deploying on Sepolia Testnet

[SquilliamX]

Hi everyone, I am getting this error where the deployed address is returning " undefined" when I console.log it. Do you know why this could be since i am waiting for the contract to deploy before i console.log it?

error:

$ yarn hardhat run scripts/deploy.js --network sepolia
yarn run v1.22.19
Grabbing Contract...
Deployed contract: undefined
Done in 24.86s.

deploy.js:

// imports
const { ethers } = require("hardhat")

// async main
async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage")// grabs the contract factory
  console.log("Grabbing Contract...") 
  const simpleStorage = await SimpleStorageFactory.deploy()
  await simpleStorage.waitForDeployment()

  console.log(`Deployed contract: ${simpleStorage.address}`)
}

//main
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.log(error);
    process.exit(1);
  });

hardhat.config.js:

require('@nomicfoundation/hardhat-toolbox');
require('dotenv').config()

/** @type import('hardhat/config').HardhatUserConfig */

const SEPOLIA_RPC_URL = process.env.SEPOLIA_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY

module.exports = {
  defaultNetwork: 'hardhat',
  networks: {
    sepolia: {
      url: SEPOLIA_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 11155111,
    },
  },
  solidity: '0.8.8',
};

console.log(contract address: ${simplestorage.target})

is the correct way to print it.
