Lesson 5: TypeError in deploy.js file

[Pratham2403]

I am getting an error after typing "node deploy.js" in the terminal : TypeError: abi is not iterable

Here is the exact error code :

TypeError: abi is not iterable
    at new Interface (/home/matrix/Blockchain/node_modules/ethers/lib.commonjs/abi/interface.js:251:25)
    at Interface.from (/home/matrix/Blockchain/node_modules/ethers/lib.commonjs/abi/interface.js:1100:16)

My code is :-

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

async function main() {
  // Our Native Blockchain is being used by the ganache application
  // http://127.0.0.1:7545

  const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
  //Private keys should not be kept open like this there are some alternatives that we will se in he future
  const wallet = new ethers.Wallet(
    "0x1dcfb8a90efb060b6b1dade3d7d2794e12df4e7d040963a8d42bb5be05241926",
    provider
  );

  const abi = new fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.abi",
    "utf8"
  );

  const binary = new fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );

  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying Please wait..........");
  // Await can only be used in async(asynchronous function)
  const contract = await contractFactory.deploy(); // Hey Wait here, the the contract deploy first
  console.log(contract);
}

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

I tried many options, I even used ChatGPT but it did not helped.

try delete SimpleStorage_sol_SimpleStorage.abi file and recompile again.

[alfaqi]

just in case, install these packages:

{
  "dependencies": {
    "dotenv": "^16.0.3",
    "ethers": "^5.7.2",
    "solc": "^0.8.7-fixed"
  }
}

and make your solidity version to pragma solidity ^0.8.7;
