Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.6.2)

[AmarRam90]

async function main() {
  // Ganache RPC:
  // http://127.0.0.1:7545

  const provider = new ethers.providers.JsonRpcProvider(
    "http://127.0.0.1:7545"
  );
  const wallet = new ethers.Wallet(
    "0x7fafd5189c4bd84b77ec7e5ca92a81a999d75131b2696faeeb3bd533f19dd5c8",
    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);
}```

Now the error is:

```Deploying, please wait...
Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.6.2)

   I have tried downgrading my ethers version to 5.6.2 but now I am clueless on how to preoceed forward with this
