Lesson 7 Error: Invalid address, processing while deploying on Rinkeby with hardhat

[LordReya]

The contract worked on the localhost, but it seems to not work correctly on the rinkeby testnet. Here is my code:

// import
// function
// main function

// function deployFunc(hre) {
// console.log("hello there!")
// }
// module.exports.default = deployFunc

//hre is same as hardhat

//nearly identical up there (but more anonymous)
// cosnt { getNamedAccounts, deployments } = hre

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

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId
    // if chainId is x use address y
    // if chainId is z use address a

    // const ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    let ethUsdPriceFeedAddress
    if (developmentChains.includes(network.name)) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        const ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    const args = [ethUsdPriceFeedAddress]
    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: args, //put price feed address
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })
    //when going for localhost or hardhat network we want to use a mock
    log("---------------------------------------")
    if (
        !developmentChains.includes(network.name) &&
        process.env.ETHERSCAN_API_KEY
    ) {
        await verify(fundMe.address, args)
    }
}
module.exports.tags = ["all", "fundme"]

This is the error code:

Hi! In your code replace: if (developmentChains.includes(network.name))
for: if (chainId == 31337)

[javierdash]

Also replace this please:
if ( !developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY

for:
if(chainId != 31337 && process.env.ETHERSCAN_API_KEY

[LordReya]

Sadly again same error...

[javierdash]

also checked if you have a file named helper-hardhat-config.js that looks like this:

const networkConfig = {
    4: {
        name: "rinkeby",
        vrfCoordinatorV2: "0x6168499c0cFfCaCD319c818142124B7A15E857ab",    
    },
}

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

module.exports = {
    networkConfig, 
    developmentChains,
}

[LordReya]

also checked if you have a file named helper-hardhat-config.js that looks like this:

const networkConfig = {
    4: {
        name: "rinkeby",
        vrfCoordinatorV2: "0x6168499c0cFfCaCD319c818142124B7A15E857ab",    
    },
}

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

module.exports = {
    networkConfig, 
    developmentChains,
}

Hmm... This is how my helper hardhat looks like:

const networkConfig = {
    4: {
        name: "rinkeby",
        ethUsdPriceFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e",
    },
    137: {
        name: "polygon",
        ethUsdPriceFeed: "0xF9680D99D6C9589e2a93a78A04A279e509205945",
    },
}

const developmentChains = ["hardhat", "localhost"]
const DECIMALS = 8
const INITIAL_ANSWER = 200000000000

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

Is it maybe because I did something wrong here?

[LordReya]

@PatrickAlphaC I again need a hero! Or from someone else in this wonderful community. I tried my best to find the issue, but nothing seems to work again. This time, no 7 hours sitting around. I'll take a break for now till I get to know what exactly is wrong.

[PatrickAlphaC]

You're getting invalid address

Error: invalid address (argument="address", value=undefined, code=INVALID_ARGUMENT, version=address/5.6.1) (argument="priceFeedAddress", value=undefined, code=INVALID_ARGUMENT, version=abi/5.6.3)

Could you do a console.log(ethUsdPriceFeedAddress) and see what you're setting that address as?

[LordReya]

You're getting invalid address

Error: invalid address (argument="address", value=undefined, code=INVALID_ARGUMENT, version=address/5.6.1) (argument="priceFeedAddress", value=undefined, code=INVALID_ARGUMENT, version=abi/5.6.3)

Could you do a console.log(ethUsdPriceFeedAddress) and see what you're setting that address as?

It's showing me the Rinkeby address that I got from the chain link documents.

[SantanuDK]

let ethUsdPriceFeedAddress  // you declared ethUsdPriceFeedAddress  with let keyword
    if (developmentChains.includes(network.name)) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
const ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"] //and here also you are trying to declare with const keyword
    }

here your are trying to declare a same variable with two different keywords which is already been declared i think that might be the problem.

[LordReya]

It was the "const" before ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]

Thank you! Helped a lot!

[PatrickAlphaC]

Awesome!

[Starmand6]

This helped me, too. Thanks, @SantanuDK!

[mattjaf]

Try pasting this in your deployment script and redeploying to see if it works. The issue might be somewhere else:

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

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

    let ethUsdPriceFeedAddress
    if (chainId == 31337) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    log("----------------------------------------------------")
    log("Deploying FundMe and waiting for confirmations...")
    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: [ethUsdPriceFeedAddress],
        log: true,
        // we need to wait if on a live network so we can verify properly
        waitConfirmations: network.config.blockConfirmations || 1,
    })
    log(`FundMe deployed at ${fundMe.address}`)

    if (
        !developmentChains.includes(network.name) &&
        process.env.ETHERSCAN_API_KEY
    ) {
        await verify(fundMe.address, [ethUsdPriceFeedAddress])
    }
}

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

[LordReya]

Thanks! I found the error. I typed const before ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]

[IbrahimGhasia]

Thanks! Found My error.

const args = [ethUsdPriceFeedAddress] const fundMe = await deploy("FundMe", { from: deployer, args: args, // put price feed address log: true, waitConfirmations: network.config.blockConfirmations || 1, })

instead of args: args, I had written args: [args]

[RowinVanAmsterdam]

Thanks, also found my error. I had defined args above the if statement instead below. Like this:

 let ethUsdPriceFeedAddress;
 const args = [ethUsdPriceFeedAddress];


    if(developmentChains.includes(network.name)) {
        const ethUsdAggregator = await get("MockV3Aggregator");
        ethUsdPriceFeedAddress = ethUsdAggregator.address;
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId as keyof typeof networkConfig].ethUsdPriceFeed;
    }


    const fundMe = await deploy("FundMe", {
