Lesson 5: TypeError: abi.map is not a function

[RamyTheEngineer]

async function main() {
  //http://127.0.0.1:7545
  const provider = new ethers.providers.StaticJsonRpcProvider(
    "http://127.0.0.1:7545"
  );
  const wallet = new ethers.Wallet(
    "0e84b59ddccb5ba19af241e6ba52ba04e56ce5bf5d9a9f79b641f3c97a643388",
    provider
  );
  const abi = new 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);
}

I am having this error:

Code breaks at this line

 const contractFactory = new ethers.ContractFactory(abi, binary, wallet);

@ramykh show your abi file, see it should be inside array [{}]

[Sami-Shafi]

Are you sure your sol file doesn't have any problems? If you are sure it's bug-free, try deleting the binary and abi file, recompile the sol file, and then run the deploy script.
