Lesson 7 log("Mocks deployed!") TypeError: Cannot read properties of undefined (reading 'indexOf')

[JuniorSua]

Hello I am having this error message come up when I run yarn hardhat deploy --tags "mocks

TypeError: Cannot read properties of undefined (reading 'indexOf')

const { network, deployments } = require("hardhat")
const {
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER,
} = require("../helper-hardhat-config")

module.exports = async ({ getNameAccounts, deloyments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNameAccounts()

    if (chainId == 31337) {
        log("local network detected! Deploying  mocks...")
        await deploy("MockV3Aggregator", {
            contract: "MockV3Aggregator",
            from: deployer,
            log: true,
            args: [DECIMALS, INITIAL_ANSWER],
        })
        log("Mocks deployed!")
        log("---------------------------------------------------------")
    }
}

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

Here is my helper-hardhat-config.js

const networkConfig = {
    4: {
        name: "rinkeby",
        ethUsdPriceFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e",
    },
    137: {
        name: "polygon",
        ethUsdPriceFeed: "OxF9680D99D6C9589e2a93a78A04A279e5092059454",
    },
    31337: {
        name: "localhost",
    },
}

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

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

Here is my 01-deploy-fund-me.js

// import
// main function
// calling main function

const { network } = require("hardhat")

// async function deployFunc() {
//     console.log("Hi!")
// }
// module.exports.default = deployFunc

// const helperConfig = require("../helper-......")
// const networkConfig = helperConfig.networkConfig
const { networkConfig } = require("../helper-hardhat-config")

const { network } = require("hardhat")

module.exports = async ({ getNamedAccounts, deployments }) => {
    //const { getNamedAccounts, deployments } = hre
    // hre.getNamedAccounts
    // hre.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"]

    // if the contract doesn't exist, we deploy a minimal version of
    // for out local testing

    // well what happens when we want to change chains?
    // when going for localhost or hardhat network we want to use a mock
    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: [
            /* Address */
        ], // put price feed address
        log: true,
    })
}

Please let me know what you think I can do to fix it... thank you so much in advance

@JuniorSua : Correct the following mistakes, I'm listing below in your mocks deploy script :

1. Correct the deployments and getNamedAccounts spelling in module.exports :

module.exports = async ({ getNameAccounts, deloyments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNameAccounts()

2. And also remove the extra coma from module.exports.tags : module.exports.tags = ["all", , "mocks"]

Corrections should be like this :

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

• Also define chainId in your module.exports like this : const chainId = network.config.chainId , I have already add this in the above correction, I made for spellings!

• module.exports.tags should look like this : module.exports.tags = ["all", "mocks"]

Just Copy & Paste all of the changes!

And run this command after that : yarn hardhat deploy --tags mocks

Perfect, Thank you so much..... I also had const { network } = require("hardhat") twice on my 01-deploy-fund-me.js
Beside that you were so helpful thank you again.
