I am on Lesson 7: hardhat FundMe . at 10:59:00 on youtube . after I run this command 01-fund-me.js :- const{networkConfig, developmentChains} = require("../helper-hardhat-config")
const { network, deployments } = 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,
log:true,
waitConfirmations: network.config.blockConfirmations || 1,
})
if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
await verify(fundMe.address,args)
}
log("____________________________")
}

Hello @arf92, the problem seems to be in the
ethUsdPriceFeedkey, make sure the address stored in thehelper-hardhat-configfile forgoerliis a string and the name of the key in the file is as wellethUsdPriceFeed.
