Lesson 9: TypeError: vrfCoordinatorV2Mock.createSubscription is not a function

[TradMod]

My Mocks are getting deployedsuccessfully but I am getting errors while deploying the contract.

My 01-deploy.js:

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

const 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.getContractFactory("VRFCoordinatorV2Mock")
        vrfCoordinatorV2address = vrfCoordinatorV2Mock.address;
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)
        subscriptionId = transactionReceipt.events[0].args.subId
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, FUND_AMOUNT)
    } else {
        vrfCoordinatorV2address = networkConfig[chainId]["vrfCoordinatorV2"];
        subscriptionId = networkConfig[chainId]["subscriptionId"];
    }

    const entranceFee = networkConfig[chainId]["entranceFee"];
    const keyHash = networkConfig[chainId]["keyHash"];
    const callbackGasLimit = networkConfig[chainId]["callbackGasLimit"];
    const interval = networkConfig[chainId]["interval"];
    const bingo = await deploy("Bingo", {
        from: deployer,
        args: [vrfCoordinatorV2address, entranceFee, keyHash, subscriptionId, callbackGasLimit, interval],
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })

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

}

module.exports.tags = ["all", "bingo"]

Help pls. Thanks

Instead of

const vrfCoordinatorV2Mock = await ethers.getContractFactory("VRFCoordinatorV2Mock");

Try this,

const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")

when I am doing this my error show getContract is not a function
