Lesson 9 : TypeError: (0 , ethers_1.getAddress) is not a function

[MrPositive0709]

I have followed Patrick to 15:19:30 but when I deploy it returns this bug :
Nothing to compile
Local network detected ! Deploying mocks...
deploying "VRFCoordinatorV2Mock" (tx: 0x72a894d215f348b1e3a4d1665d1332c1096776aa1d6f2d3b0dacaafb1ae71b7f)...: deployed at 0x5FbDB2315678afecb367f032d93F642f64180aa3 with 2527447 gas
Mock Deployed

An unexpected error occurred:

This is my 01-deploy-raffle.js file :
`const { network, ethers } = require("hardhat");

const {
developmentChains,
networkConfig,
} = require("../helper-hardhat-config");

const VRF_SUB_FUND_AMOUNT = ethers.utils.parseEther("2");

module.exports = async function ({ getNamedAccounts, deployments }) {
const { deploy, log } = deployments;
const { deployer } = await getNamedAccounts();
const chainId = network.config.chainId;

let vrfCoordinatorV2Address, subscriptionId;
if (developmentChains.includes(network.name)) {
const vrfCoordinatorV2Mock = await ethers.getContract(
"VRFCoordinatorV2Mock"
);
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address;
const transactionResponse = await vrfCoordinatorV2Mock.createSubscription();
const transactionReceipt = await transactionResponse.wait(1);
subscriptionId = transactionReceipt.events[0].args.subId;
//fund the subscription
// usually need the link token on a real network
await vrfCoordinatorV2Mock.fundSubscription(
subscriptionId,
VRF_SUB_FUND_AMOUNT
);
} else {
vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"];
subscriptionId = networkConfig[chainId]["subscriptionId"];
}

const gasLane = networkConfig[chainId]["gasLane"];
const entranceFee = networkConfig[chainId]["entranceFee"];
const callbackGasLimit = networkConfig[chainId]["callbackGasLimit"];
const interval = networkConfig[chainId]["interval"];

const args = [
vrfCoordinatorV2Address,
entranceFee,
gasLane,
subscriptionId,
callbackGasLimit,
];
const raffle = await deploy("Raffle", {
from: deployer,
args: args,
log: true,
waitComfirmations: network.config.blockConfirmations || 1,
});

if (
!developmentChains.includes(network.name) &&
process.env.ETHERSCAN_API_KEY
) {
log("Verifying...");
await verify(raffle.address, args);
}

log("-------------------------------");
};

module.exports.tags = ["all", "raffle"];

I have asked ChatGPT and it said that there is conflict between the version of Hardhat and the @nomiclabs/hardhat-ethers plugin and followed the instructs that ChatGPT gave me but it did not work

Make sure, you are using ethersV5 instead of ethersV6,
and please share your repo

[AyodejiKomolafe]

if you are using ethers v6:
instead of ethers.getContract()
use
ethers.getContractAt()

also instead of vrfCoordinatorV2Mock.address
use
vrfCoordinatorV2Mock.target

also this line is important so as to get the VRFCoordinatorV2Mock address
const contractAddress = (await deployments.get("VRFCoordinatorV2Mock")).address;

so your code ends up looking like this

if (developmentChains.includes(network.name)) {
   const contractAddress = (await deployments.get("VRFCoordinatorV2Mock")).address;
    const vrfCoordinatorV2Mock = await ethers.getContractAt(
      "VRFCoordinatorV2Mock",
      contractAddress
    );
    vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target;
    const transactionResponse = await vrfCoordinatorV2Mock.createSubscription();
    const transactionReceipt = await transactionResponse.wait(1);```

Changing:
const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
to
const vrfCoordinatorV2Mock = await deployments.get("VRFCoordinatorV2Mock");
fixed it for me.
Thanks!
