Lesson 9: Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.6.2)

[BrysonHall]

I was doing the Patrick Collins tutorial and link got this error Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.6.2) when I was running hh deploy
I got this error for the 01.deploy-raffle.js.

01.deploy-raffle.js code:

const { network, ethers } = require("hardhat")
const { developmentChains, networkConfig } = 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 vrfCoordinatorV2Adress, subscriptionId

    if (developmentChains.includes(network.name)) {
        const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Adress = vrfCoordinatorV2Mock.address
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionRecipt = await transactionResponse.wait(1)
        subscriptionId = transactionRecipt.events[0].args.subId
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
    } else {
        vrfCoordinatorV2Adress = networkConfig[chainId]["vrfCoordinatorV2"]
        subscriptionId = 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 = [
        vrfCoordinatorV2Adress,
        entranceFee,
        gasLane,
        subscriptionId,
        callbackGasLimit,
        interval,
    ]
    const raffle = await deploy("Raffle", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmation: network.config.blockConfirmation || 1,
    })

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

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

[mattjaf]

you spelled vrfCoordinatorV2Adress wrong its vrfCoordinatorV2Address

err it might not be the exact issue

double check your args and makes sure their set properly,

double check your helper-hardhat-config file.

[BrysonHall]

Fixing the argument array fixed my problem. I appreciate the help :)

[armontej]

how did you fix your argument array i am running into the same error

[BrysonHall]

Check to see if the keys in the networkConfig object in the helper-hardhat-config.js file match the argument array you set up in 01-deploy-raffle.js.

Here is the argument array I used in 01-deploy-raffle.js:

const args = [
        vrfCoordinatorV2Adress,
        entranceFee,
        gasLane,
        subscriptionId,
        callbackGasLimit,
        interval,

[armontej]

nice man glad you were able to solve this issue, as was i!

[BrysonHall]

Glad it worked for you to :) Happy coding!

[Izmanovich]

In case someone is having this error for 01-deploy-raffle.js you can try this:

1 - Check if you can see Local network detected! in the logs when you run hh deploy (npm/yarn hardhat deploy) for 00-deploy-mocks.js.
2 - If you can see it, add callbackGasLimit: "500000" to networkConfig[31337] in helper-hardhat-config.js. E.g:

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

I hope this can help someone!

I got the same error, Thank you it worked for me

I'm getting the same error but none of these worked for me.

FWIW I had this error, and it turned out i was spelling entranceFee wrong (as entracefee instead). So even if it says bigValue error, check your helper-hardhat-config file and your deploy scripts and make sure that all of your terms are spelled correctly (or at least match from one file to the next.)

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.

I tried this and it did not change anything. I am still getting the same problem. Here is my code:
