Argument of type '{ value: BigNumber; }' is not assignable to parameter of type 'Overrides & { from?: string | Promise<string> | undefined; }'

I am developing a smart contract with solidity(version 0.8.0) at buildspace here is my code snippet in TypeScript(4.5.x)/JavaScript, and node 16.13.x

...
const waveContractFactory = await hre.ethers.getContractFactory("WavePortal");
  const waveContract = await waveContractFactory.deploy({
    value: hre.ethers.utils.parseEther("0.1"),
});

...

The above code is written in a file called: run.ts To execute the code, this is the command: npx hardhat run scripts/run.ts

Here is the head of the error I got with its tail truncated:

error TS2345: Argument of type '{ value: BigNumber; }' is not assignable to parameter of type 'Overrides & { from?: string | Promise<string> | undefined; }'.
  Object literal may only specify known properties, and 'value' does not exist in type 'Overrides & { from?: string | Promise<string> | undefined; }'.

7     value: hre.ethers.utils.parseEther("0.1"),
....

with "7" above showing the line where the error occurred.

I didn't know where the error is coming from. The code keeps failing for run.ts/js

I am trying to fund my smart contract with 0.1 ether.

Here is the snippet to my smart contract:

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.0;

import "hardhat/console.sol";

contract WavePortal {
...
 constructor() {
    console.log("Hello, Multiverse... I am Smart Contract WavePortal");
  }
...
}

So after making research for some hours, I found the answer here.

I had to add a payable modifier to the contract's constructor and it work:

contract WavePortal {
...
 constructor() payable {
    console.log("Hello, Multiverse... I am Smart Contract WavePortal");
  }
...
}
