Lesson 5 - Ethers.js Simple Storage: Error: invalid address or ENS name

[Tosinkoa]

Pls why am I getting this error? Error: invalid address or ENS name (argument="name", value=undefined, code=INVALID_ARGUMENT, version=providers/5.6.8)

Here is my code snippet:

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

const main = async () => {
  try {
    const provider = new ethers.providers.JsonRpcProvider("HTTP://127.0.0.1:7545");
    const wallet = new ethers.Wallet("d7fe65e618df184d0cd3edf4ad96620e11511322516295c7b292f37b4a7eef96", provider);
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
    const binary = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8");

    const nonce = await provider.getTransactionCount();

    const tx = {
      nonce: nonce,
      gasPrice: 20000000000,
      gasLimit: 1000000,
      to: null,
      value: 0,
      data: "0x6080604...", //I have to shorten the bin number here
      chainId: 5777,
    };
    const sentTxResponse = await wallet.sendTransaction(tx);
    await sentTxResponse.wait(1);
    console.log(sentTxResponse);
    
  } catch (err) {
    console.error(err);
    process.exit(1);
  }
};

This will solve your problem.
To get the transaction count, we get it from the wallet, not provider

const nonce = await wallet.getTransactionCount();

Also, https://github.com/PatrickAlphaC/ethers-simple-storage-fcc/blob/main/deploy.js
You can refer to the two points that I mentioned here in the script written by Patrick.

It still throws the error.

const ethers = require("ethers");

const main = async () => {

    await sentTxResponse.wait(1);
    console.log(sentTxResponse);

1. I copy-pasted your code and had to change the
   await provider.getTransactionCount();
   to
   await wallet.getTransactionCount();
   and this resolved the error that you're getting.

2. Also, change the network id from 5777 to 1337

3. Also, ensure that your Ganache is running on WSL network as shown in the image below

This is likely an issue with windows.

Could you try one of these?

Everything works fine now when I try again this morning, thank you so much for helping me. Here is what my code looks like.

import ethers from "ethers";
import fs from "fs-extra";
import dotenv from "dotenv";

dotenv.config();

const main = async () => {
  try {
    const provider = new ethers.providers.JsonRpcProvider("HTTP://127.0.0.1:7545");
    const wallet = new ethers.Wallet("e7375568eb10c3f411b3494c5e657ac2a26d7dddda08d1bb3388dfa6540ce1e6", provider);
    const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
    const binary = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8");

    const nonce = await wallet.getTransactionCount();
    const tx = {
      nonce: nonce,
      gasPrice: 20000000000,
      gasLimit: 6721975,
      to: null,
      value: 0,
      data: "0x6080604053...",
      chainId: 1337,
    };
    const sentTxResponse = await wallet.sendTransaction(tx);
    await sentTxResponse.wait(1);
    console.log(sentTxResponse);

  } catch (err) {
    console.error(err);
    process.exit(1);
  }
};

main();
