TypeError: Cannot read properties of undefined (reading 'toHexString'), when trying to run w. alchemy

[armontej]

I am at the part in section 5 where we are using alchemy to get a fake address and run our deploy.js code. After copying the private key from alchemy and the rpc, when i try to run node delpoy.js i get this error = "TypeError: Cannot read properties of undefined (reading 'toHexString')"

**const ethers = require("ethers");
const fs = require("fs-extra");
require("dotenv").config();

async function main() {
// http://127.0.0.1:7545
// compile them in our code
// compile them seperatly
const provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL);
// const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider); *Below using encrypted key
const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf8");
let wallet = new ethers.Wallet.fromEncryptedJsonSync(
encryptedJson,
process.env.PRIVATE_KEY_PASSWORD
);
wallet = await wallet.connect(provider);
const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
const binary = fs.readFileSync(
"./SimpleStorage_sol_SimpleStorage.bin",
"utf8"
);
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 Address: ${contract.address});

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);
});**

@armontej
It is not getting the key properly, and you do not need a private key from Alchemy, you just need an RPC_URL from there, private key should be taken from MetaMask.

mkae sure you have 0x in front of your private key
