error : invalid address

[chrismogab]

Hi i am still a beginner in coding, when i try to run yarn hardhat deploy on this code i get this error : ERROR processing /Users/chrismogab/hardhat-fund-me/deploy/01-deploy-fund-me.js

Error: invalid address (argument="address", value=undefined, code=INVALID_ARGUMENT, version=address/5.6.1) (argument="priceFeedAddress", value=undefined, code=INVALID_ARGUMENT, version=abi/5.6.4)

so i assume my error is from my 01 deploy-fund-me-js folder, here is the folder can you please help me find where the problem is?

#866

const { getNamedAccounts } = require("hardhat")
const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { network } = require("hardhat")
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 (developmentChains.includes(network.name)) {
    const ethUsdAggregator = await deployments.get("MockV3Aggregator")
    ethUsdPriceFeedAddress = ethUsdAggregator.address
} else {
    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,
})
if (!developmentChains.includes && process.env.ETHERSCAN_API_KEY) {
    await verify(fundMe.address, args)
}
log("-------")

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

Could you send your helper-hardhat-config.js file? Thank you

[chrismogab]

thank you for answering my helper-hardhat is :

const networkConfig = {
4: {
name: "rinkeby",
ethUsdPricFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e",
},
137: {
name: "polygon",
ethUsdPricFeed: "0xF9680D99D6C9589e2a93a78A04A279e509205945",
},
}
const developmentChains = ["hardhat", "localHost"]
const DECIMALS = 8
const INITIAL_ANSWER = 200000000000
module.exports = {
networkConfig,
developmentChains,
DECIMALS,
INITIAL_ANSWER,
}

Yeah, found the problem - there is a typo inside your networkConfig. Please correct it by copying this: ethUsdPriceFeed. Hope this helped!

[chrismogab]
