Lesson 6: TypeError: (0 , ethers_1.getAddress) is not a function

[affanmustafa]

I am following along the code as it is being done in the video and getting the error as shown in the title (Timestamp 9:20:00). I was using ethers v6 but then I rolled back to v5.4.0 as v6 was giving me many errors as well. My deploy.js looks like this

//import
const { ethers, run, network } = require("hardhat");

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

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

    // We cannot verify a contract that we have deployed on Hardhat since it is a local network
    console.log(network.config);
    if (network.config.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
        await simpleStorage.deployTransaction.wait(6);
        await verify(simpleStorage.address, []);
    }

    //get current value from the smart contract
    const currentValue = await simpleStorage.retrieve();
    console.log(`Current value is ${currentValue}`);

    //update the current value
    const transactionResponse = await simpleStorage.store(7);
    await transactionResponse.wait(1);
    const updateValue = await simpleStorage.retrieve();
    console.log(`Updated value is ${updateValue}`);
}

// async function verify(contractAddress, args) {
const verify = async (contractAddress, args) => {
    console.log("Verifying contract...");
    try {
        await run("verify:verify", {
            address: contractAddress,
            constructorArguments: args,
        });
    } catch (e) {
        if (e.message.toLowerCase().includes("already verified")) {
            console.log("Already Verified");
        } else {
            console.log(e);
        }
    }
};

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

And my block-number.js looks like this:

require("@nomicfoundation/hardhat-toolbox");
//const task = require("hardhat/config");

task("block-number", "Prints the current block number").setAction(
    async (taskArgs, hre) => {
        const blockNumber = await hre.ethers.provider.getBlockNumber();
        console.log(`Current block number is ${blockNumber}`);
    }
);
module.exports = {};

After running yarn hardhat node and yarn hardhat run scripts/deploy.js --network localhost I get the following error:

TypeError: (0 , ethers_1.getAddress) is not a function at main (/hardhat/hardhat-tutorial/scripts/deploy.js:6:34)

see here #5735

let me know if it works with you
if not share your repo

Hi. I tried that, but didn't work unfortunately. I'm still getting the same error. Here is the repo

[alfaqi]

you need to update "hardhat": "^2.14.1", package to "hardhat": "^2.16.0",

then import them into hardhat.config.js file, like this

require("@nomiclabs/hardhat-etherscan");
require("@typechain/hardhat");
require("@nomiclabs/hardhat-ethers");
require("dotenv").config();
require("./tasks/block-number");

and modify block-number.js like this:

require("@typechain/hardhat");
require("@nomiclabs/hardhat-ethers");

getting problem with "@nomicfoundation/hardhat-ethers".
install @nomiclabs/hardhat-ethers instead "@nomicfoundation/hardhat-ethers".
then import them into hardhat.config.js file and deploy.js file , like this
require("@nomiclabs/hardhat-ethers");

[amine08]

you need to add require("@nomiclabs/hardhat-ethers"); to hardhat.config.js

I can only mark one as an answer but for anyone who has the same problem, please be sure to try out both the solutions. One mentioned by @amine08 and the other by @alfaqi as they both worked for me.
