ReferenceError: wallet is not defined

I am getting this error at 08:03:50 time in video that encountered the problem

amey242@DESKTOP-NPUSTB1:~/hh-fcc/ethers-simple-storage$ node deploy.js
ReferenceError: wallet is not defined
    at main (/home/amey242/hh-fcc/ethers-simple-storage/deploy.js:20:69)
    at Object.<anonymous> (/home/amey242/hh-fcc/ethers-simple-storage/deploy.js:47:1)

The line of code is:

const contractFactory = new ethers.ContractFactory(abi, binary, wallet)
    console.log("Deploying, please wait...")
    const contract = await contractFactory.deploy() // Stop here!! Wait for contract to deploy
    await contract.deployTransaction.wait(1)
    console.log(`Contract Addresss: ${contract.address}`)

    // console.log("Let's deploy with only transaction data!");
    // const nonce = await wallet.getTransactionCount();
    // const tx = {
    //   nonce: nonce,
    //   gasPrice: 20000000000,
    //   gasLimit: 1000000,
    //   to: null,
    //   value: 0,
    //   chainId: 1337,
    // };
    // const sentTxResponse = await wallet.sendTransaction(tx);
    // await sentTxResponse.wait(1);
    // console.log(sentTxResponse);

    const currentFavoriteNumber = await contract.retrieve()
    console.log(`Current Favorite Number: ${currentFavoriteNumber.toString()}`)
    const transactionResponse = await contract.store("7")
    const transactionReceipt = await transactionResponse.wait(1)
    const updatedFavoriteNumber = await contract.retrieve()
    console.log(`Updated favorite number is: ${updatedFavoriteNumber}`)
}
main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

Did you forget there lines in your deploy.js script:

let wallet = new ethers.Wallet.fromEncryptedJsonSync(
    encryptedJson,
    process.env.PRIVATE_KEY_PASS
  );
  wallet = wallet.connect(provider);

Thanks. I had commented it out that line in my code. Thanks for the help

Problem lies here:

let provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
let wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider)

Make sure whether the above, .env, PRIVATE_KEY and provider are correct.
