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

[tedyu]

I am using hardhat 2.18.0
I am able to compile my contract.
When I issue the following command:

npx hardhat run scripts/deploy.js

I get the following error:

TypeError: Cannot read properties of undefined (reading 'deployContract')
    at main (/Users/zhihongyu/contract-gl/scripts/deploy.js:15:33)
    at Object.<anonymous> (/Users/zhihongyu/contract-gl/scripts/deploy.js:30:1)

This is the start of my deploy.js:

const hre = require("hardhat");

async function main() {
  const currentTimestampInSeconds = Math.round(Date.now() / 1000);
  const unlockTime = currentTimestampInSeconds + 60;

  // const lockedAmount = hre.ethers.parseEther("0.001");

  const lock = await hre.ethers.deployContract("My_Smart_Contract", [unlockTime], {
    value: 1,
  });

I don't seem to find deployContract in js files:

find node_modules/ -name '*.js' -exec grep deployContract {} \; -print

Any hint is welcome.

are you using the ethers plugin?
