Lesson 14 Error: invalid BigNumber value // When trying to deploy Mocks

[xKeywordx]

Hello guys,

I am getting this error

After solving 2 or 3 errors in a row myself, I got stuck here when trying to deploy Mocks.
It seems that I manage to deploy the VRFCoordinatorV2Mock.sol, but it fails to deploy MockV3Aggregator.sol.

00-deploy-mocks.sol code:

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

const BASE_FEE = "250000000000000000"; // 0.25 is this the premium in LINK?
const GAS_PRICE_LINK = 1e9; // link per gas, is this the gas lane? // 0.000000001 LINK per gas

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments;
    const { deployer } = await getNamedAccounts();
    const chainId = network.config.chainId;
    // If we are on a local development network, we need to deploy mocks!
    if (chainId == 31337) {
        log("Local network detected! Deploying mocks...");
        await deploy("VRFCoordinatorV2Mock", {
            from: deployer,
            log: true,
            args: [BASE_FEE, GAS_PRICE_LINK],
        });
        await deploy("MockV3Aggregator", {
            from: deployer,
            log: true,
            args: [DECIMALS, INITIAL_PRICE],
        });

        log("Mocks Deployed!");
        log("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
        log(
            "You are deploying to a local network, you'll need a local network running to interact"
        );
        log(
            "Please run `yarn hardhat console --network localhost` to interact with the deployed smart contracts!"
        );

It's my first time posting smth like this on GitHub, please excuse me if it's not exactly right. Any help would be much appreciated.

I see you are trying to import DECIMALS and INITIAL_PRICE from helper-hardhat but they are not defined in your helper hardhat add this lines to your helper hardhat and try again const DECIMALS = "18" const INITIAL_PRICE = "200000000000000000000"

Hey, thanks for the help.
I just realized that I reused the helper-hardhat-config.js file from the lottery smart contract tutorial, and instead of mintFee, I had entry raffle fee.

Thanks for the help, I updated the helper-hardhat-config.js file following Patrick's repo, but kept it for Goerli instead of Sepolia and now this problem is solved. I encountered a new one, saying that ethers.getNamedAccounts is not a function.

But at least my Mocks are getting deployed now.

[xKeywordx]

Now I am getting this new error. I managed to find some info online about a similar problem with ethers.getContractAt, which apparently was a problem between hardhat and ethers "fighting" together.

Bu I have a slightly different problem here with "getNamedAccounts"

@xKeywordx You should leave your repo link so we can see your all code, this error is inside 02-deploy-random-ipfs-nft.js file.

[xKeywordx]

@alymurtazamemon thanks for the help sir, but I managed to fix it.
In my 02-deploy file I was using ethers.getNamedAccounts("VRFCoordinatorV2Mock"); instead of ethers.getContract(("VRFCoordinatorV2Mock");.

That fixed the issue and I was able to upload the files to Pinata.
