Lesson 9: invalid address (argument="address", value=undefined, code=INVALID_ARGUMENT, version=address/5.6.1) (argument="vrfCoordinatorV2", value=undefined, code=INVALID_ARGUMENT, version=abi/5.6.4)

I am getting this Error invalid address (argument="address", value=undefined, code=INVALID_ARGUMENT, version=address/5.6.1) (argument="vrfCoordinatorV2", value=undefined, code=INVALID_ARGUMENT, version=abi/5.6.4)

hello for share code you need change from """ to ``` top and bottom each code to make sure easy people to read and also help the error

Thanks, @MuhammadLuqman-99 Edited the Stuff

@Cryptobaba1 Follow this discussion #527

And also see this guide, How to Ask a Question Guide

[Sunil-Reddy-Gummalla]

Hi @ali-thegilfoyle
Thanks for Guide
I went through #527 but it is not helping me
When I tried console.log(args) it threw Cannot access 'args' before initialization

[Sunil-Reddy-Gummalla]

Finally Figured it
in 01-deploy-Raffle.js

let vrfCoordinatorV2Address

    if (developmentChains.includes(network.name)) {
        const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        const vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)
        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)

After defining let vrfCoordinatorV2Address
I am using const before it in if condition That's why it is getting as Invalid
Thanks @ali-thegilfoyle
