Javascript – How to wait for the deployment transaction of the contract to be mined

**I want to deploy a smart contract and wait for the deployment transaction of the contract to be mined but i am running into some error **
**version used **

 "dotenv": "^16.3.1",
 "ethers": "^6.6.4",
 "fs-extra": "^11.1.1",
 "solc": "^0.8.7-fixed"

code:

const { ethers, JsonRpcProvider } = require("ethers");
const fs = require("fs-extra");
require("dotenv").config();

async function main() {
  const provider = new JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider); 
  const abi = fs.readFileSync("./simple_storage_sol_SimpleStroge.abi", "utf8");
  const bytecode = fs.readFileSync("./simple_storage_sol_SimpleStroge.bin", "utf8");

  const contractFactory = new ethers.ContractFactory(abi, bytecode, wallet);
  console.log("Deploying......");
  const contract = await contractFactory.deploy();
  await contract.deployTransaction.wait(1); 
  console.log(`Contract address: ${contract.address}`);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

i have used await contract.deployed(); suggested by chatgpt
but it’s giving the similar error

error
