Lesson 7, 10:59 "Error: invalid address"

[Totiruzi]

When I tried to run the command "yarn hardhat deploy --network rinkeby"
I get the error:
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)
at Logger.makeError (/home/danigab/Desktop/BlockChain/hardhat/hardhat-fund-me-coo/node_modules/@ethersproject/logger/src.ts/index.ts:261:28)

this is the code in my 01-deploy-fund.js

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

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

let ethUsdPriceFeedAddress
if(developementChains.includes(network.name)) {
const ethUsdAggregator = await 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(!(developementChains.includes(network.name)) && process.env.ETHERSCAN_API_KEY) {
await verify(fundMe.address, args)
}
log("____________________________________________________________________________")
}

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

Can I see your helper-hardhat-config file? make sure you have the right ethUsdpriceFeed address in the rinkeby section

[adityabhattad2021]

I guess problem is that chain link no longer support rinkeby as it is depricated.

sure !!
`
const networkConfig = {
// 31337: {
// name: "localhost",
// },
4: {
name: "rinkeby",
ethUsdPrice: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e"
},
137: {
name: "polygon",
ethUsdPrice: "0xF9680D99D6C9589e2a93a78A04A279e509205945"
}
}

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

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

change ethUsdPrice to ethUsdPriceFeed in these two lines

ethUsdPrice: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e"
ethUsdPrice: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e"

You are trying to access ethUsdPriceFeed in you deploy-fund-me.js when you have named the variable ethUsdPrice
Make this change and see if it works.

This worked like a charm. Thanks a million @othaime-en for you time, effort and help !!!!

Push to GitHub and link it here, I will look into it.

If you are sure of problems not persisting in your code, it must be Rinkeby—which should be fixed by using Goerli.

@krakxn merged the request but still have the same error

" hardhat-fund-me-coo/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)"

when I run
yarn hardhat deploy --network rinkeby

Hey @Totiruzi try the fix suggestions I've given you above and see if it works

[Totiruzi]

Thanks @othaime-en
I don't know how I mist your solution advice!!!
Thanks a bunch.
It works just fine now!!
Learning continues !!!

[Totiruzi]

@krakxn Thanks a million, people like you makes the world go round and learning experience less tedious. I really apreciate your time taken to examine my code on github and searching for a solution. I owe it to others coming behind and more.
I appreciate!!!
Thanks a bunch once again !!!!
