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

[SamarthBagga]

here is my code for the 99-update-front-end.js file-

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

const FRONT_END_ADDRESSES_FILE = "../nextjs-smartcontract-lottery/constants/contractAddresses.json"
const FRONT_END_ABI_FILE = "../nextjs-smartcontract-lottery/constants/abi.json"

module.exports = async () => {
    if (process.env.UPDATE_FRONT_END) {
        console.log("Updating frontend")
        await updateContractAddresses()
        await updateAbi()
        console.log("frontend written!")
    }
}

async function updateAbi() {
    const raffle = await ethers.getContract("Raffle")
    fs.writeFileSync(FRONT_END_ABI_FILE, raffle.interface.format(ethers.utils.FormatTypes.json))
    console.log("added abi")
}

async function updateContractAddresses() {
    const raffle = await ethers.getContract("Raffle")
    const chainId = network.config.chainId.toString()
    const contractAddresses = JSON.parse(fs.readFileSync(FRONT_END_ADDRESSES_FILE, "utf8"))
    if (network.config.chainId.toString() in contractAddresses) {
        if (!contractAddresses[chainId].includes(await raffle.getAddress())) {
            contractAddresses[chainId].push(await raffle.getAddress())
        }
    } else {
        contractAddresses[chainId] = [await raffle.getAddress()]
    }
    fs.writeFileSync(FRONT_END_ADDRESSES_FILE, JSON.stringify(contractAddresses))
    console.log("added address")
}
module.exports.tags = ["all", "frontend"]

getting this error when running yarn hard deploy-

Error: ERROR processing /home/samarth/web3/hardhat-smartcontract-lottery/deploy/99-update-front-end.js:

check the paths are correct
const FRONT_END_ADDRESSES_FILE = "../nextjs-smartcontract-lottery/constants/contractAddresses.json"
and const FRONT_END_ABI_FILE = "../nextjs-smartcontract-lottery/constants/abi.json" so the script can reach them

In ethers 6, you can use the formatJson() function to get the same thing that Patrick.
The doc : https://docs.ethers.org/v6/api/abi/#Interface-formatJson

The line to write the contract ABI :

fs.writeFileSync(FRONT_END_ABI_FILE, raffle.interface.formatJson());
