Lesson 9 TypeError: 1000000000 is not a function

[angelDova]

I am getting an error at around the 15: 20 mark when deploying the mocks. "TypeError: 1000000000 is not a function". I'd appreciate anybodys help. Thank you!

Here is my 00-deply-mocks.js:

const { network } = require("hardhat")
const { developmentChains } = require("../helper-hardhat-config")

const BASE_FEE = ethers.utils.parseEther("0.25") //0.25 is the premium . It costs 0.25 link per request
const GAS_PRICE_LINK = 1e9

     module.exports = async function ({ getNamedAccounts, deployments }) {
        const { deploy, log } = deployments
        const { deployer } = await getNamedAccounts()
        const args = [BASE_FEE, GAS_PRICE_LINK]

        if (developmentChains.includes(network.name)) {
            log("Local network detected! deploying mocks...")
            // deploy a mock vrfCoordinator...
            await deploy("VRFCoordinatorV2Mock", {
                from: deployer,
                log: true,
                args: args,
            })
            log("Mocks Deployed!!!")
            log("----------------------------")
        }
    }


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

helper-hardhat-config.js:

const { ethers } = require("hardhat")

const networkConfig = {
    4: {
        name: "rinkeby",
        vrfCoordinatorV2: "0x6168499c0cFfCaCD319c818142124B7A15E857ab",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc", // 30 gwei
        subscriptionId: "0",
        callbackGasLimit: "500000", // 500,000
        interval: "30",
    },
    31337: {
        name: "hardhat",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc", // 30 gwei
        callbackGasLimit: "500000", // 500,000
        interval: "30",
    },
}

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

module.exports = {
    networkConfig,
    developmentChains,
}

Lot of things are wrong here

1. there is opening parenthesis after 1e^9 in deploy mocks line 5 so remove that and then close all parathesis correctly.
2. test folder containing VRFCoordinatorV2Mock.sol should be inside of contracts folder since we know all the solidity code should be inside contract folder only.
3. Also in deploy-raffle you are not referring callbackgaslimit from helper.hardhat.config.js correctly on line 27 it should be callbackGasLimit not calbackGasLimit.
4. In deploy-raffle on line 19 fundSubsrciption function should have two parameters subscriptionId and fundamount
   Basically you should replace line from this await VRFCoordinatorV2Mock.fundSubscription(subscriptionId) to this await VRFCoordinatorV2Mock.fundSubscription(subscriptionId,VRF_SUB_FUND_AMOUNT).

After fixing these it will work fine

Thank you so much! I fixed all my errors and redeployed. It's working perfect now.

@angelDova

I think you by mistake put a parenthesis in line 5 after '1e9'

const GAS_PRICE_LINK = 1e9(

the closing parenthesis is in line 29, so the whole deploy script basically becomes the input to a function.

remove the parenthesis and see if it works

Thank you! this helped!
