Defender Timelock contract verification failing

Hi @Prash_Cha

I've gone ahead and verified the contract for you: https://goerli.etherscan.io/address/0xB0c1500b1Da0873e5a4c28F28aaDdB350080C175#code

I was able to do this through the hardhat-etherscan plugin as such:

I defined this as TimelockController.sol in the contracts folder of my Hardhat project:

//SPDX-License-Identifier: Unlicense
pragma solidity ^0.8.4;

import "@openzeppelin/contracts/governance/TimelockController.sol";

Then, I defined this as arguments.js

module.exports = [
    180,
    [
        "0x309fe87adafb481199862eadf2ac6abd1fc446bc"
    ],
    [
        "0x0000000000000000000000000000000000000000",
    ]
];

and ran the following command:

npx hardhat verify --constructor-args arguments.js --network goerli 0xB0c1500b1Da0873e5a4c28F28aaDdB350080C175

Make sure you install the right version of openzeppelin's contract library. In package.json:

"dependencies": {
    "@openzeppelin/contracts": "4.3.1",
    ...
}

Defender is currently deploying version 4.3.1 of the Timelock Controller contract.

Hope that helps!
