Lessson:7 : Error while deploying Mocks at 10:49.[SOLVED]

[ritesh798]

I have got this wierd error while deploying mocks

deploy-Mock.js

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

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

  if (developmentChains.includes(network.name)) {
    log("Local network detected! Deploying Mocks...");
    const deployed = await deploy("MockV3Aggregator", {
      contract: "MockV3Aggregator",
      from: deployer,
      log: true,
      args: [DECIMALS, INITIAL_ANSWER],
    });
    log("Mocks Deployed");
    log("________________________________________");
  }
};

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

helper-hardhat-config.js

const networkConfig = {
  4: {
    name: "rinkby",
    ethUsdPriceFeed: 0x8a753747a1fa494ec906ce90e9f37563a8af630e,
  },
  137: {
    name: "polygon",
    ethUsdPriceFeed: 0xf9680d99d6c9589e2a93a78a04a279e509205945,
  },
};

const developmentChains = ["hardhat", "localhost"];
const DECIMALS = 8;
const INITIAL_ANSWER = 200000000000;
module.exports = {
  networkConfig,
  developmentChains,
  DECIMALS,
  INITIAL_ANSWER,
};

• This should be in your hardhat.config.js file:

namedAccounts: {
        deployer: {
            default: 0, // here this will by default take the first account as deployer
            1: 0, // similarly on mainnet it will take the first account as deployer. Note though that depending on how hardhat network are configured, the account 0 on one network can be different than on another
        },

• This should be there in your helper-hardhat.config.js file, and also correct the typo (rinkby) in it to rinkeby:

31337: {
        name: "localhost",
    },

• And lastly, copy directly my changes for your deploy-mocks file:

const { network } = require("hardhat")
const {
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER,
} = require("../helper-hardhat-config")
module.exports = async ({ getNamedAccounts, deployments }) => { // { getNamedAccounts, deployments } = hre
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId
    // We need to deploy mocks for local networks
    if (chainId == 31337) {
        log("Local network detected! Deploying mocks...")
        await deploy("MockV3Aggregator", {
            contract: "MockV3Aggregator", // To be really specific
            from: deployer,
            log: true,
            args: [DECIMALS, INITIAL_ANSWER],
        })
        log("Mocks deployed!")
        log("---------------------------------------------------------------")
    }
}

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

Hope this solves your problem :D

@ritesh798 show your hardhat config file.
