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

[SamarthBagga]

I am getting this when running -

yarn hardhat deploy

to update the frontend to fill the abi.json file. The file paths are correct as the contractaddress.json file is being filled. Here is the code-

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"]

Change second line to: const { fs } = require("fs");
If this doesn't solve your problem, share your package.json

[SamarthBagga]

@Adelani10 after changing the second line to your suggestion i get this error-

Alright delete your package.json, copy and paste this in there:-

{
  "devDependencies": {
    "@chainlink/contracts": "^0.6.1",
    "@nomicfoundation/hardhat-ethers": "^3.0.0",
    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13",
    "@nomiclabs/hardhat-etherscan": "^3.1.7",
    "@nomiclabs/hardhat-waffle": "^2.0.6",
    "chai": "^4.3.4",
    "dotenv": "^16.3.1",
    "ethereum-waffle": "^3.4.0",
    "ethers": "^5.7.2",
    "hardhat": "^2.17.1",
    "hardhat-deploy": "^0.11.36",
    "hardhat-gas-reporter": "^1.0.9",
    "prettier": "^3.0.2",
    "prettier-plugin-solidity": "^1.1.3",
    "solidity-coverage": "^0.8.1"
  }
}

Also, put these at the top of your hadhat.config file

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

Finally, delete your node-modules and yarn.lock, then run yarn install, then try to update the frontend again.

hi @Adelani10 i have made my project completely according to ethers v6 if i revert to v5 then it will cause other problems. Does the abi file need to have curly brackets or should it be completely blank for this to work?

[Adelani10]

Oh, my bad then, if you’ve gone for the v6 i’m not sure i can help. The abi doesn’t need that, just the contract address. If you could post a link yo your repo.

[SamarthBagga]

@Adelani10 here is my repo-

I fixed this by replacing this line-

    fs.writeFileSync(FRONT_END_ABI_FILE, raffle.interface.format(ethers.utils.FormatTypes.json))

with this line-

    fs.writeFileSync(FRONT_END_ABI_FILE, JSON.stringify(raffle.interface.format("json")))

[ugur17]

This seems like works, but it prints abi wrongly, that's why didn't work for me. If anyone had the same thing;
const abi_source = require("../artifacts/contracts/Raffle.sol/Raffle.json");
async function updateAbi() {
const raffle = await ethers.getContract("Raffle");
fs.writeFileSync(ABI_FILE, JSON.stringify(abi_source["abi"]));
}

This fixed my issue.

[ypszn]

I also got my ABI wrongly. Thanks for this. Worked perfectly!

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());
