Lesson 5: Error while deploying deploy.js

[Balaji-97]

Hey everyone, I got the below error while deploying the contract.

Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.6.8)
    at Logger.makeError (/home/balaji/hh-fcc/ethers-simple-storage-fcc/node_modules/@ethersproject/logger/lib/index.js:233:21)
    at Logger.throwError (/home/balaji/hh-fcc/ethers-simple-storage-fcc/node_modules/@ethersproject/logger/lib/index.js:242:20)

    at Object.throw (/home/balaji/hh-fcc/ethers-simple-storage-fcc/node_modules/@ethersproject/providers/lib/json-rpc-provider.js:29:53)
    at rejected (/home/balaji/hh-fcc/ethers-simple-storage-fcc/node_modules/@ethersproject/providers/lib/json-rpc-provider.js:21:65) {
  reason: 'could not detect network',
  code: 'NETWORK_ERROR',
  event: 'noNetwork'
}

It would be great if someone would help me out solving this issue, below is my deploy.js code.

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

async function main() {
  //   http://127.0.0.1:7545
  const provider = new ethers.providers.JsonRpcProvider(
    "HTTP://172.29.224.1:7545"
  );
  const wallet = new ethers.Wallet(
    "8fa00bd5f41c86b8f5e8af1923267aa687151183e1c929980e802863caf8abb7",
    provider
  );
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf-8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy();
  console.log(contract);
}

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

Hello krakxn, here is the repository link that you have requested:

https://github.com/Balaji395/network-error-for-deploy.js/tree/main

[krakxn]

Made a PR there which shall fix the logical error in your program and it should most likely work now. If it does not, the problem lies in the external provider, ie, Ganache - which too we can diagnose. But the program itself is perfect now. Hope this helped!

[krakxn]

Uhm.. why would you decline the PR if you want help? It resolves errors which will fix the issue
