Lesson 6 error: TypeError: simpleStorage.deployed is not a function

[SquilliamX]

Hi guys, I am confused as to why my code is throwing an error when it doesn't for Patrick, can anyone explain this to me and how to fix it please? I am using sepolia instead of Rinkeby, but I don't think that is the problem here.

error:

$ yarn hardhat run scripts/deploy.js --network sepolia
yarn run v1.22.19
$ /home/smartchain/code/foundry-f23/hardhat-simple-storage/node_modules/.bin/hardhat run scripts/deploy.js --network sepolia

deploy.js:

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

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

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

hardhat.config.js:

require('dotenv').config()

Yes unfortunately the .deployed() function has been deprecated.
Instead use simpleStorage.waitForDeployment()

Thank you I was looking for this. Where did you find that information exactly? Can you share a link to it? Thanks 😃

Also now I am getting this error where the deployed address is returning a undefined. 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

Use .target instead of .address
It is also new to @nomiclabs/hardhat-toolbox library
I recommend copying the dependencies in Patrick's github repos and deleteing your node-modules folder.
Then reinstalling them using yarn
