Lesson 7: Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.7.0)

[huelight]

I tried running the mock script and keep getting invalid big number, anyone hav an idea where this error is coming from. The code is below

00-deploy-fund-me.js

const { network } = require("hardhat")
const { DECIMALS, INITIAL_ANSWER } = require("../helper-hardhat-config")

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    if (chainId == 31337) {
        log("Local network detected! Deploying mocks...")
        await deploy("MockV3Aggregator", {
            contract: "MockV3Aggregator",
            from: deployer,
            log: true,
            args: [DECIMALS, INITIAL_ANSWER],
        })
        log("Mocks Deployed")
        log("-----------------------------------------")
    }
}
module.exports.tags = ["all", "mocks"]

@huelight Make sure these variables are not undefined DECIMALS, INITIAL_ANSWER, otherwise leave you repo link I will test it and let you know the error location.

The variables DECIMALS, INITIAL_ANSWER are defined. Here is the link to the repo. Thanks.

@huelight I was talking about undefined. Here is the problem

module.export = {
    networkConfig,
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER,
}

It is module.exports not module.export and due to it these variables were undefined inside deploy files.

Thanks a lot, problem fixed. You're amazing 👌
