Lession 6: I am getting following error.

[harry2855]

Time : 8:41:15

const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage")
 console.log("Deploying")
 const simpleStorage = await SimpleStorageFactory.deploy()
 await simpleStorage.deployed()

In the above code I am getting this error:
TypeError: no matching function (argument="key", value="deployed", code=INVALID_ARGUMENT, version=6.6.1)

Probably, I am getting error in 'await simpleStorage.deployed()' . But why?
Also, I am not able to access any of simplStorage function. It is giving error on .address .retrieve as well.

Could you provide your SimpleStorage code as well as the full script for the deploy.js.

I have copy pasted SimpleStoragecode

  People[] public people;

  mapping(string => uint256) public nameToFavoriteNumber;

  function store(uint256 _favoriteNumber) public {

  function retrieve() public view returns (uint256) {

}

Deploy.js

const { ethers } = require("hardhat");

async function main(){
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage")
  console.log("Deploying")
  const simpleStorage = await SimpleStorageFactory.deploy()
  console.log(simpleStorage.address)
  

}

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

This is due to you using tool-box. Updated your package.json with this dependecies:

{
  "name": "hardhat-simple-storage-fcc",
  "devDependencies": {
    "@nomiclabs/hardhat-ethers": "^2.0.4",
    "@nomiclabs/hardhat-etherscan": "^3.0.0",
    "@nomiclabs/hardhat-waffle": "^2.0.2",
    "chai": "^4.3.4",
    "ethereum-waffle": "^3.4.0",
    "ethers": "^5.5.3",
    "hardhat": "^2.16.0",
    "hardhat-gas-reporter": "^1.0.7",
    "solidity-coverage": "^0.7.18"
  },
  "dependencies": {
    "dotenv": "^14.2.0",
    "prettier-plugin-solidity": "^1.0.0-beta.19"
  },
  "scripts": {
    "lint": "yarn prettier --check .",
    "lint:fix": "yarn prettier --write ."
  }
}

And in your hardhat.config.js instead of require("@nomicfoundation/hardhat-toolbox"); use require require("@nomiclabs/hardhat-waffle");

Thank for this, i use it and it work, deploy the hardhat-simple-storage to sepolia

In version 6 this is the method from BaseContract class which is inherited by the contract you are trying to deploy:
async waitForDeployment()
So something like this
await simpleStorage.waitForDeployment();
should work.
