I can help you with that. However, I must point out that the provided code snippet contains syntax errors and potential problems.

Here is an updated version of the article:

Ethereum: TypeError cannot read properties of Undefined

When working with Ethereum smart contracts using Hardhat, it is important to deal with potential errors that may occur during the execution of your contracts. A common problem is trying to access properties of an object that are not properly initialized.

In this case, we encounter a TypeError when we try to call the “parseEther()” parameter on the Escrow object. This error occurs because the “Escrow” object is not properly defined or initialized before we try to access it.

Let’s take a closer look at what can cause this problem:

const { ethers } = require("hardhat");
const { time } = required("@nomicfoundation/hardhat-network-helpers");
description("Escrow", function () {
give Escrow;
give escrow;
beforeEach(async () => {
// Initialize the escrow contract with Hardhat's ContractFactory API
const EscrowContractFactory = await ethers.getContractFactory("Escrow");
Escrow = await EscrowContractFactory.deploy();
await Escrow.constructor();
// Set the escrow contract address as an environment variable for easy access
process.env.SECROW_CONTRACT_ADDRESS = await Escrow.address;
// Set the escrow contract ABI and event functions
const escrowABI = [
{
revenues: [],
statechanges: [],
payable: false,
returns: []
}
];
const eventFunctions = ["escrowEscrow", "escrowPay"];
// Call the deploy method to initialize the escrow contract
await new ethers.Contract(ScrowContractAddress, escrowABI, ScrowContract.abi)(process.env.SECROW_CONTRACT_ADDRESS);
});
it("Should test escrow function correctly", async function () {
const escrow = await this.SecrowContract();
// ... the rest of your code

Here are the changes made to resolve the issue:

• Added variable “ScrowContractAddress” and initialized it with the address of the delivered contract.

• Before use, call the method “deploy” in the class “ScrowContract” to ensure that the contract is initialized correctly.

• Set the environment variable SECROW_CONTRACT_ADDRESS to store the address of the deployed escrow contract.

You can fix this issue and resolve it in your own codebase as follows:

const { ethers } = require("hardhat");
description("Escrow", function () {
give Escrow;
give escrow;
beforeEach(async () => {
const ScrowContractAddress = "0x..."; // Replace with the actual address of the delivered contract.
Escrow = await ethers.getContractFactory("Escrow");
Escrow = await Escrow.deploy(ScrowContractAddress);
await Escrow.constructor();
process.env.SECROW_CONTRACT_ADDRESS = scrow.address;
});
it("Should I test the escrow function properly", async function () {
const escrow = await this.SecrowContract();
// ... the rest of your code

In this updated version, I replaced the hardcoded variable process.env.SECROW_CONTRACT_ADDRESS with a more dynamic approach that uses the actual address of the deployed contract.
