contract address is null in transaction receipt

[Divyanshu-Madhav]

Hi,
I have ran into an issue
this is my deploy.js code :

const { ethers , run ,network} = require("hardhat");
async function main() {
  const simpleStorageFactory = await ethers.getContractFactory("simplestorage");
  console.log("deploying contact ...");
  const simpleStorage = await simpleStorageFactory.deploy();
  await simpleStorage.waitForDeployment();
  console.log(
    "simple storage contract address is",
    await simpleStorage.getAddress()
  );
  if(network.config===11155111 && process.env.ETHERSCAN_API_KEY){
    await simpleStorage.deployTransaction.wait(1);
    await verify(simpleStorage.getAddress(),[]);
  }
  const transactionResponse = await simpleStorage.store("abhay", 50);
  const transactionreceipt=await transactionResponse.wait(5);
  console.log(transactionResponse);
  console.log(transactionreceipt);
  console.log(await simpleStorage.friend[0]);
}
async function verify(contractAddress,args)
{
  console.log("verifying contract ...");
  try{
  await run("verify:verify",{
    address:contractAddress,
    contructorArguments:args,
  })}
  catch(e){
    if(e.message.toLowerCase().includes("already verified")){
      console.log("Already Verified");
    } else {
      console.log(e);
    }
  }
}
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.log(error);
    process.exit(1);
  });

and this is my hardhat config file :

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();
//require("@nomiclabs/hardhat-etherscan");
const sepolia_rpc_url=process.env.SEPOLIA_RPC_URL;
const private_key=process.env.PRIVATE_KEY;
const etherscan_api_key=process.env.ETHERSCAN_API_KEY;
/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  defaultNetwor:"hardhat",
  networks:{
    sepolia:{
      url:sepolia_rpc_url,
      accounts:[private_key],
      chainId:11155111,
      gasPrice: 30000000000,
    }
  },
  solidity: "0.8.24",
  etherscan:{
    api_key:etherscan_api_key
  }
};

and this is the command I used to run the file yarn hardhat run scripts/deploy.js --network sepolia and this is the output I am getting :

simple storage contract address is 0x991C443574228A925Cbd862e785dAB7B45ce36cb

undefined

this undefined should also be not there as I want the output as the array and also my smartContract file is fully compiled and is correct.
Can anybody please help me with this issue.

Edit: after changing the api_key to apiKey and defaultNetwor to defaultNetwork in hardhat.config file ,I am now getting the follwing error :
