Lesson 9: vrfCoordinatorV2Mock.createSubscription is not a function

[ypszn]

The terminal throws in this error anytime i try to deploy and i have tried everything i can to fix it. Can someone pls help me?

Error: ERROR processing C:\Users\user\hh-fcc\hardhat-smartcontract-lottery-fc
c\deploy\01-deploy-raffle.js:
TypeError: vrfCoordinatorV2Mock.createSubscription is not a function

This is the code from my deploy-raffle.js script

 if (developmentChains.includes(network.name)) {
        const vrfCoordinatorV2Mock = await deployments.get("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)

        if (
            transactionReceipt &&
            transactionReceipt.events &&
            transactionReceipt.events.length > 0
        ) {
            subscriptionId = transactionReceipt.events[0].args.subId

            // here we are creating the subscription
            // after we have created the subscription. we need to fund the subscription
            // to fund the subcription on a real network you will usually need a link token
            // the current iteration the mock allows us to fund the subcription without ink token
            await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
        } else {
            console.error("No events found in the transaction receipt or events array is empty.")
            // Handle this scenario, perhaps retry or report an error
        }
    } else {
        vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"]
        subscriptionId = networkConfig[chainId]["subscriptionId"]
    }

try instead

const vrfCoordinatorV2Mock = await deployments.get("VRFCoordinatorV2Mock")
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target

do

const contractAddress = (await deployments.get('VRFCoordinatorV2Mock')).address;
const vrfCoordinatorV2Mock = await ethers.getContractAt(
        'VRFCoordinatorV2Mock',
        contractAddress
        );
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address;
