Lesson 5: Unable to deploy contract on Ganache: "node deploy.js"

[0xSaurabhSharma]

I am @7:07:00 in the course and now I want to deploy contract on Ganache

Contract is compiled properly, but I could not deploy it

RPC provider is correct
Private Key is correct

MY CODE

const ethers = require("ethers");
const fs = require("fs-extra");

async function main() {
  const provider = new ethers.providers.JsonRpcProvider(
    "http://127.0.0.1:7545"
  );

  const wallet = new ethers.Wallet(

    "8dc63eacadd298a96da0ce8ea16b0d93a461ab5eb213c5c38f4b159e38eb50ef",
    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(); 
  console.log(contract);
}

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

MY OUTPUT

root@LAPTOP-G4PDCC17:~/hh-fcc/ethers-simple-storage# yarn compile

does your metamask detect your ganache server?
