Lesson18, Error: cannot estimate gas

[gingercatLovesHerWife]

I ran into this error when I am trying to deploy governor contract. [1:06:46:49]

Below is my code.

import { HardhatRuntimeEnvironment } from "hardhat/types";
import { DeployFunction } from "hardhat-deploy/types";
import {
    VOTING_DELAY,
    VOTING_PERIOD,
    QUORUM_PERCENTAGE,
} from "../helper-hardhat-config";

const deployGovernorContract: DeployFunction = async function (
    hre: HardhatRuntimeEnvironment
) {
    // @ts-ignore
    const { getNamedAccounts, deployments } = hre;
    const { deploy, log, get } = deployments;
    const { deployer } = await getNamedAccounts();
    const governanceToken = await get("GovernanceToken");
    const timeLock = await get("TimeLock");
    log("----------------------------------------------------");
    log("Deploying Governor...");
    const governorContract = await deploy("GovernorContract", {
        from: deployer,
        args: [
            governanceToken.address,
            timeLock.address,
            // QUORUM_PERCENTAGE,
            // VOTING_PERIOD,
            // VOTING_DELAY,
        ],
        log: true,
        estimatedGasLimit: 10000000,
    });
};

export default deployGovernorContract;`

First, I ran into this error:
`Error: expected 2 constructor arguments, got 5`
I checked GovernorContract.sol, and commented the extra three arguments. Here is my constructor of GovernorContract.sol
`    constructor(IVotes _token, TimelockController _timelock)
        Governor("GovernorContract")
        GovernorSettings(
            1, /* 1 block */
            45818, /* 1 week */
            0
        )
        GovernorVotes(_token)
        GovernorVotesQuorumFraction(4)
        GovernorTimelockControl(_timelock)
    {}

Then, I ran into this error.
Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (reason="Transaction reverted: trying to deploy a contract whose code is too large", method="estimateGas", transaction={"from":"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266","data":"0x6101606040523...

I added the estimatedGasLimit argument with the initial amount 1000. The Error changed:
Error: insufficient funds for intrinsic transaction cost [ See: https://links.ethers.org/v5-errors-INSUFFICIENT_FUNDS ] (error={}, method="estimateGas", transaction={"from":"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266","gasLimit":{"type":"BigNumber","hex":"0x03e8"},"data":"0x61016...

But as I manually increased the argument, the error message chaged back to "cannot estimate gas" as showed before.

To remove
Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (reason="Transaction reverted: trying to deploy a contract whose code is too large", method="estimateGas", transaction={"from":"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266","data":"0x6101606040523...

Try adding
allowUnlimitedContractSize: true, in your hardhat.config.ts

I was having the same issue and this worked, thanks @Muhammad-Abdullah012!
