Lesson 10: Error: ENOENT: no such file or directory, open '../../nextjs-smartcontract-lottery-fcc/constants/contractAddresses.json'

My code is

const { ethers, network } = require("hardhat");
const fs = require("fs");

const FRONT_END_ADDRESSES_FILE =
  "../../nextjs-smartcontract-lottery-fcc/constants/contractAddresses.json";

const FRONT_END_ABI_FILE =
  "../../nextjs-smartcontract-lottery-fcc/constants/abi.json";

module.exports = async function () {
  if (process.env.UPDATE_FRONT_END) {
    console.log("Updating front end...");
    updateContractAddresses();
    updateAbi();
  }
};

async function updateAbi() {
  const raffle = await ethers.getContract("Raffle");
  fs.writeFile(
    FRONT_END_ABI_FILE,
    raffle.interface.format(ethers.utils.FormatTypes.json)
  );
}

async function updateContractAddresses() {
  const raffle = await ethers.getContract("Raffle");
  const chainId = network.config.chainId.toString();
  const currentAddresses = JSON.parse(
    fs.readFileSync(FRONT_END_ADDRESSES_FILE, "utf-8")
  );
  if (chainId in contractAddresses) {
    if (!contractAddresses[chainId].includes(network.address)) {
      contractAddresses[chainId].push(raffle.address);
    }
  }
  {
    currentAddresses[chainId] = [raffle.address];
  }
  fs.writeFileSync(FRONT_END_ADDRESSES_FILE, JSON.stringify(currentAddresses));
}

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

I have tried both
this

const FRONT_END_ADDRESSES_FILE =
  "../../nextjs-smartcontract-lottery-fcc/constants/contractAddresses.json";

const FRONT_END_ABI_FILE =
  "../../nextjs-smartcontract-lottery-fcc/constants/abi.json";

and this

const FRONT_END_ADDRESSES_FILE =
  "../nextjs-smartcontract-lottery-fcc/constants/contractAddresses.json";

const FRONT_END_ABI_FILE =
  "../nextjs-smartcontract-lottery-fcc/constants/abi.json";

I got this error

Error: ENOENT: no such file or directory, open '../../nextjs-smartcontract-lottery-fcc/constants/contractAddresses.json

@umairahmed88 First of all make sure in your frontend project folder at the root level you should have a folder named constants and inside it, you should have these files contractAddresses.json and abi.json.

In addition to this, you should make sure your blockchain code project and frontend code project are inside the same folder and then you are using the paths accordingly.

If you are sure you have done all of these, then show me your folders structure.

thankyou for considering me! I had some typo, I filtered
