*ERROR

[RoboCrypter]

@thatboyankit : In your 01-deploy-lottery.js file :

Change this line of code from this : waitConfirmations: waitBlockConfirmations

To : waitConfirmations: network.config.blockConfirmations || 1

[aaankeet]

@thatboyankit : wait then, Now, I was just working with your deploy, contract and helper now, I'm cloning the entire repo,

Give me few minutes!

ok.

[RoboCrypter]

@thatboyankit : And also : In your 01-deploy-raffle.js file

Remove the ! from this if statement

if (!developmentChains.includes(network.name)) {
    await vrfCoordinatorV2Mock.addConsumer(
        subscriptionId.toNumber(),
        lottery.address
    )
}

[RoboCrypter]

@thatboyankit : And finally : It is working I'm making one last PR in your repo check it out!

[RoboCrypter]

@thatboyankit : Corrected you hardhat.config.js file:

1. Change this line from this : require("dotenv")

   To : require("dotenv").config()

2. And also In your rinkeby network you have spelled account , It shoud be accounts

   Now, It will work for sure!
