TypeError: Cannot read properties of undefined (reading 'entranceFee')

Hello,
I get the error: TypeError: Cannot read properties of undefined (reading 'entranceFee')
This happens when I try to deploy the contract.

Here's is my deploy script:

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

const VRF_SUB_FUND_AMOUNT = ethers.utils.parseEther("30")

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.getContract("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)
        subscriptionId = transactionReceipt.events[0].args.subId
        // We need to fund this subscription
        // Fund the subscription is done with link token on a real network
        // However, this mock allows us to fund the subscription without the link token
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
    } else {
        vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"]
        subscriptionId = networkConfig[chainId]["subsrciptionId"]
    }

    const entranceFee = networkConfig[chainId]["entranceFee"]
    const gasLane = networkConfig[chainId]["gasLane"]
    const callbackGasLimit = networkConfig[chainId]["callbackGasLimit"]
    const interval = networkConfig[chainId]["interval"]
    const args = [vrfCoordinatorV2Address, entranceFee, gasLane, callbackGasLimit, interval]

    const raffle = await deploy("Raffle", {
        from: deployer,
        log: true,
        args: args,
        waitConfirmations: network.config.blockConfirmations || 1,
    })

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

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

@blaynejosh : Can your send me your repo link!

[RoboCrypter]

@blaynejosh : I have made PRs in your repo, Kindly merge them, for them to count in hacktoberfest event as my contributions!

After merging them, It should work just fine!

Let me know, If it resolves your issue!

[blaynejosh]

Okay...thank you @abossofmyself ...I'll give it a try

[blaynejosh]

Thanks it worked...
However, I couldn't spot the difference

can you Show me what you changed/corrected
?

[RoboCrypter]

@blaynejosh : Sure!

- In your helper-hardhat The mistakes was :

1. You have putted all your networks in the goerli chainId.
2. You have not putted the callbackGasLimit in your hardhat chainId.

Your networkConfig looked like this before the fix :

const networkConfig = {
    5: {
        5: {
            name: "goerli",
            vrfCoordinatorV2: "0x2Ca8E0C643bDe4C2E08ab1fA0da3401AdAD7734D",
            entranceFee: ethers.utils.parseEther("0.01"),
            gasLane: "0x79d3d8832d904592c0bf9818b621522c988bb8b0c05cdc3b15aea1b6e8db0c15",
            subscriptionId: "0",
            callbackGasLimit: "500000",
            interval: "30",
        },
        31337: {
            name: "hardhat",
            entranceFee: ethers.utils.parseEther("0.01"),
            gasLane: "0xcc294a196eeeb44da2888d17c0625cc88d70d9760a69d58d853ba6581a9ab0cd",
            interval: "30",
        },
        // 137: {
        //     name: "polygon",
        //     vrfCoordinatorV2: "0xAE975071Be8F8eE67addBC1A82488F1C24858067",
        //     entranceFee: ethers.utils.parseEther("0.01"),
        //     gasLane: "0xcc294a196eeeb44da2888d17c0625cc88d70d9760a69d58d853ba6581a9ab0cd",
        //     subscriptionId: "0",
        //     callbackGasLimit: "500000",
        //     interval: "30",
        // },
    },
}

It should be like this, with all the fixes, I made :

const networkConfig = {
    5: {
        name: "goerli",
        vrfCoordinatorV2: "0x2Ca8E0C643bDe4C2E08ab1fA0da3401AdAD7734D",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0x79d3d8832d904592c0bf9818b621522c988bb8b0c05cdc3b15aea1b6e8db0c15",
        subscriptionId: "0",
        callbackGasLimit: "500000",
        interval: "30",
    },
    31337: {
        name: "hardhat",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xcc294a196eeeb44da2888d17c0625cc88d70d9760a69d58d853ba6581a9ab0cd",
        callbackGasLimit: "500000",
        interval: "30",
    },
    // 137: {
    //     name: "polygon",
    //     vrfCoordinatorV2: "0xAE975071Be8F8eE67addBC1A82488F1C24858067",
    //     entranceFee: ethers.utils.parseEther("0.01"),
    //     gasLane: "0xcc294a196eeeb44da2888d17c0625cc88d70d9760a69d58d853ba6581a9ab0cd",
    //     subscriptionId: "0",
    //     callbackGasLimit: "500000",
    //     interval: "30",
    // },
}

- In your deploy script the mistakes was,

1. You have the subscriptionId spelling mistake.
2. You have not putted the subscriptionId in the args.
