Lesson 9: TypeError: no matching function (argument="key", value="address", code=INVALID_ARGUMENT, version=6.6.6)

[affanmustafa]

I am running into the following error:
TypeError: no matching function (argument="key", value="address", code=INVALID_ARGUMENT, version=6.6.6) in my deploy/01-delpoy-raffle.js (I understand there is a type in the file name, I will fix that). I can't figure out why I am getting this error. For reference, the ethers version I am using in this is 6.6.6.

Ethers version 6 made some changes like address to target or await .. getAddress(), so will be like this
const contract = await contractFactory.getAddress();

[affanmustafa]

Could you elaborate on this more? Where do I need to make this fix?

[alfaqi]

You have two ways to fix this issue.
one way is change any address to target or await .. getAddress()
like this, in 01-delpoy-raffle.js file change
from

        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address;

to

        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target;

or

        vrfCoordinatorV2Address = await vrfCoordinatorV2Mock.getAddress();

this means you will use ethersV6.
OR
the other way is, downgrade the ethers version to ^5
change these lines in package.json file

    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers",
    "ethers": "^6.6.6",

to

    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13",
    "ethers": "^5.7.2",

then run yarn or yarn install to install these packages.
or run this command

yarn add --dev @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers@^0.3.0-beta.13 ethers@^5.7.2

and you have to change this ethers.parseEther(...); to ethers.utils.parseEther(...); in all files
you have another issue in helper-hardhat-config.js file, add this line into 31337: { object

        callbackGasLimit: "500000", //500,000

I suggest you downgrade to version 5, so you can follow along with the course.

what if both :

vrfCoordinatorV2Address = await vrfCoordinatorV2Mock.getAddress();

and

vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target;

do not work ?

i get:

TypeError: invalid value for Contract target (argument="target", value=null, code=INVALID_ARGUMENT, version=6.7.1)

with any of the three versions.

01-deploy-raffle.js:

const { network, ethers } = require("hardhat")
const { developmentChains, networkConfig } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")
const { Log } = require("ethers")

const VRF_SUB_FUND_AMOUNT = ethers.parseEther("1") // 1 Ether, or 1e18 (10^18) Wei

module.exports = async function ({ getNamedAccounts, deployments }) {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId
    let vrfCoordinatorV2Address, subscriptionId

    if (chainId == 31337) {
        const vrfCoordinatorV2Mock = await ethers.getContractAt("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = await vrfCoordinatorV2Mock.getAddress()
        const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionResponse.wait(1)
        subscriptionId = 1
        // Fund the subscription
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
    } else {
        // testnet
        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,
    ]
    const raffle = await deploy("Raffle", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })

    if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        log("Verifying...")
        await verify(raffle.address, args)
    }
    log("Raffle Deployed!")
    log("------------------------------")
}
module.exports.tags = ["all", "raffle"]

@alfaqi maybe sharing my repo can help: https://github.com/Astronaut828/SolidityCourse/tree/main/hh-solidity/hardhat-smartcontract-lottery

[alfaqi]

you have to add the deployer while getting the contract, like this

        const vrfCoordinatorV2Mock = await ethers.getContractAt("VRFCoordinatorV2Mock", deployer)

[Astronaut828]

Thank you, I must have missed that while changing it a few times. 🙏
@alfaqi now I am back at square one:
Error: Invalid Chai property: revertedWith

At this point i don't even want to install chai again (the only solution I seem to find online) since this is what caused the last headache.

[alfaqi]

Ok, I hope you find the solution.
instead of revertedWith(...) use reverted or revertedWithCustomError

Hi @affanmustafa, @Astronaut828
The difference between dependencies and devDependencies
In package.json, regular dependencies are packages that are required for your production-ready site or app to work. Production-ready means the online version of your website or app that the audience experiences.
devDependencies are packages used for development purposes, e.g for running tests or transpiling your code.
