Lesson 9: Error: ERROR processing 01-deploy-raffle.js: Error: invalid BigNumber value...

[su-adam]

I have tried everything to get my my Deploy-raffle to deploy, Any help would be great

01-deploy-raffle

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

const VAF_SUB_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 (chainId == 31337) {
        const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)
        subscriptionId = transactionReceipt.events[0].subId
        //Fund the subscription
        //Ususally, you'd neeed the link token on a real network
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VAF_SUB_FUND_AMOUNT)
    } else {
        vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"]
        subcriptionId = networkConfig[chainId]["subscriptionId"]
    }

    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, subscriptionId, callbackGasLimit, interval]
    const raffle = await deploy("Raffle", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: networks.config.blockConfirmations

    })

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

Try taking the commas out of your callbackGasLimit value (so use "500000" instead of "500,000")

[su-adam]

Hey, thanks for the response. I have taken out the commas and still have the same error message

[technophile-04]

In your helper-hardhat-config you have a spelling mistake callbackGasLinit it should be callbackGasLimit. I hope you find it .

Corrected one :

helper-hardhat-config

const { ethers } = require("hardhat")



const networkConfig = {
    4: {
        name: "rinkeby",
        vrfCoordinatorV2: "0x6168499c0cFfCaCD319c818142124B7A15E857ab",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc",
        subscriptionId: "0",
-       callbackGasLinit: "500,000",
+      callbackGasLimit : "500000"
         interval: "30",


    },
    31337: {
        name: "hardhat",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc",
-       callbackGasLinit: "500,000",
+      callbackGasLimit : "500000"
        interval: "30",

    }
}

const developmentChains = ["hardhat", "localhost"]


module.exports = {
    networkConfig,
    developmentChains,
}

[su-adam]

Thank you for this, even after I change in spelling I have the same error message "Error: invalid BigNumber"

[technophile-04]

01-deploy-raffle

const raffle = await deploy("Raffle", {
        from: deployer,
        args: args,
        log: true,
-        waitConfirmations: networks.config.blockConfirmations
+   waitConfirmations: 1

    })

Since networks this variable is not defined try using 1 number instead there

[su-adam]

Hey, I tried as you said and I still get the same error. I have tried it with a comma after, with it in quote marks, each time I end up with the same error message

const raffle = await deploy("Raffle", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: 1
``

[technophile-04]

Try consol.log(args) above this function please share the screenshot maybe we can debug and see if args has any undefined fields

Also there is problem inside if block :

if (chainId == 31337) {
        const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)
-        subscriptionId = transactionReceipt.events[0].subId
+      subscriptionId = transactionReceipt.events[0].args.subId
        //Fund the subscription
        //Ususally, you'd neeed the link token on a real network
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VAF_SUB_FUND_AMOUNT)
    } else {
        vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"]
        subcriptionId = networkConfig[chainId]["subscriptionId"]
    }

I would suggest you to refer https://github.com/PatrickAlphaC/hardhat-smartcontract-lottery-fcc this and try matching both deploy and helper-hardhat-config files

IT WORKED!!!! Thank you so much :D

transactionReceipt.events[0].args.subId
This code is the root cause of this issue. It returns a bigNumber so just convert it into a String.
Like this - (transactionReceipt.events[0].args.subId).toString()

Only Change the code that is inside your IF statement.
