Lesson 9: Hardhat Smart Contract Lottery ----> HardhatError: HH700: Artifact for contract "VRFCoordinatorV2Mock" not found.

[chiranjeev13]

I am getting a error while deploying the project

this is my 01-deploy-raffle.js file

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

const FUND_AMOUNT = "1000000000000000000000";

module.exports = async ({ getNamedAccounts, deployments }) => {
  const { deploy, log } = deployments;
  const { deployer } = await getNamedAccounts();
  const chainId = network.config.chainId;
  let vrfCoordinatorV2Address, subscriptionId;

  if (chainId == 31337) {
    // create VRFV2 Subscription
    const vrfCoordinatorV2Mock = await ethers.getContract(
      "VRFCoordinatorV2Mock"
    );
    vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address;
    const transactionResponse = await vrfCoordinatorV2Mock.createSubscription();
    const transactionReceipt = await transactionResponse.wait();
    subscriptionId = transactionReceipt.events[0].args.subId;
    // Fund the subscription
    // Our mock makes it so we don't actually have to worry about sending fund
    await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, FUND_AMOUNT);
  } else {
    vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"];
    subscriptionId = networkConfig[chainId]["subscriptionId"];
  }
  const waitBlockConfirmations = developmentChains.includes(network.name)
    ? 1
    : VERIFICATION_BLOCK_CONFIRMATIONS;

  log("----------------------------------------------------");
  const arguments = [
    vrfCoordinatorV2Address,
    subscriptionId,
    networkConfig[chainId]["gasLane"],
    networkConfig[chainId]["keepersUpdateInterval"],
    networkConfig[chainId]["raffleEntranceFee"],
    networkConfig[chainId]["callbackGasLimit"],
  ];
  const raffle = await deploy("Raffle", {
    from: deployer,
    args: arguments,
    log: true,
    waitConfirmations: waitBlockConfirmations,
  });

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

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

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

and this is the error i am getting..

I even tried to change ethers.getContract("VRFCoordinatorV2Mock" );to
ethers.getContractAt("VRFCoordinatorV2Mock");

But then i got this error

I am having the same issue

[SatamSai]

@sparrow313 check if artifacts>@chainlink>mocks>VRFCoordinatorV2Mock exists

[sparrow313]

https://github.com/sparrow313/raffle_smartContract/tree/equious

yes it exists

[SatamSai]

there is a spelling mistake on line 16
replace addresss with address it will work
