Lesson 6 TypeError: Cannot read properties of undefined (reading 'url')

[Bhavik-punmiya]

I am unable to add network everytime , I run " yarn hardhat scripts/deploy.js " I get these error " TypeError: Cannot read properties of undefined (reading 'url') " . I tried finding a solution on StackExchange and StackOverflow but couldn't understand any of those,

• Timestamp : (08:41:44) Networks in Hardhat

Please Let me know If i have done something wrong while following tutorial

Hardhat.config.json

require("@nomicfoundation/hardhat-toolbox");
require("dotenv")


/** @type import('hardhat/config').HardhatUserConfig */
const SEPOLIA_RPC_URL = process.env.SEPOLIA_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY

module.exports = {
  solidity: "0.8.7",
  networks:{
    accounts: [PRIVATE_KEY],
    url: process.env.SEPOLIA_RPC_URL,
    chainId: 11155111,
  }
};

Error

$ "F:\HardHat Blockchain fcc\Hardhat simple-storage-fcc\node_modules\.bin\hardhat" run scripts/deploy.js
An unexpected error occurred:

TypeError: Cannot read properties of undefined (reading 'url')

error Command failed with exit code 1.

deploy.js

const {ethers} = require("hardhat");
require("dotenv")
require('hardhhat.config.js')
async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory(
    "SimpleStorage"
  );
  console.log("Deploying , please wait... ")
  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.deployed();

  // what's a private key 
  // what's rpc url
}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

@Bhavik-punmiya I think you forgot the network object here;

networks:{
  accounts: [PRIVATE_KEY],
  url: process.env.SEPOLIA_RPC_URL,
  chainId: 11155111,
}

it should be like this;

networks:{
  sepolia: {
       accounts: [PRIVATE_KEY],
       url: process.env.SEPOLIA_RPC_URL,
       chainId: 11155111,
  }
}
