Try updating your network.name !developmentChains.includes(network.naem) && to !developmentChains.includes(network.name) &&

[celalaksu]

Thank you @FerraroSoftware . I fixed it but the same error persists.

When i use address directly ethUsdPriceFeedAddress = "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e" instead of ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"] It gives this error

@celalaksu In 01-deploy-fund-me.js file, Can you console chainId and tell me what output you are getting?

[celalaksu]

Thank you @rodriguesnavil. There was an syntax mistake about chainId. I fixed it . But i have same error TypeError: Cannot read properties of undefined (reading 'length') Chain Id is 4. I tried orj repo and i get same error. Is there any installation I forget? I added RINKEBY_RPC_URL, PRIVATE_KEY from metamask rinkeby testnet ( and added to .env file without "0x" ), ETHERSCAN_API_KEY, COINMARKETCAP_API_KEY to .env file.

require("dotenv").config()
require("@nomiclabs/hardhat-etherscan")
require("@nomiclabs/hardhat-waffle")
require("hardhat-gas-reporter")
require("solidity-coverage")
require("hardhat-deploy")

/**
 * @type import('hardhat/config').HardhatUserConfig
 */
const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY
const COINMARKEKETCAP_API_KEY = process.env.COINMARKEKETCAP_API_KEY

module.exports = {
    //solidity: "0.8.8",
    solidity: {
        compilers: [{ version: "0.8.8" }, { version: "0.6.6" }],
    },
    defaultNetwork: "hardhat",
    networks: {
        rinkeby: {
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 4,
            blockConfirmations: 6,
        },
    },
    gasReporter: {
        enabled: true,
        outputFile: "gas-report.txt",
        noColors: true,
        currency: "USD",
        coinmarketcap: COINMARKEKETCAP_API_KEY,
        token: "MATIC",
    },
    etherscan: {
        apiKey: ETHERSCAN_API_KEY,
    },
    namedAccounts: {
        deployer: {
            default: 0,
            1: 0,
            4: 1,
        },
    },
}

[PatrickAlphaC]

Update the namedaccounts section:

    namedAccounts: {
        deployer: {
            default: 0,
        },
    },

[celalaksu]

Thank you @PatrickAlphaC. It worked

[sadityakumar9211]

I faced the same issue and this solution worked for me too. But I am a little confused, why did this happen in the first place? Why adding chainId: index key-value pair in the deployer was creating this error? Would someone please explain this?
