lesson 9 Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.7.0)

[pratokko]

hello please help me solve this BigNumber issue https://github.com/pratokko/hh-lottery.git

[alymurtazamemon]

@pratokko Console log the args in deploy raffle file and see which variable is undefined in it.

[pratokko]

here is what i have ``` 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("5")

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 trasactionReceipt = await transactionResponse.wait(1)
    subscriptionId = trasactionReceipt.events[0].args.subscriptionId
    await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
} else {
    vrfCoordinatorV2Address = 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 = [
    vrfCoordinatorV2Address,
    entranceFee,
    gasLane,
    subscriptionId,
    callbackGasLimit,
    interval,
]
console.log(args)

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

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

log("-------------------------------------------------------------------------")

}

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

@pratokko what did you see in the terminal when you console log this console.log(args)?

[pratokko]

this is what was printed

@pratokko Update these lines;

subscriptionId = trasactionReceipt.events[0].args.subId
await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)

[pratokko]

thanks a lot man it worked, Thank you
