Lesson 6: HH8 Error

[SandyTampaBay]

i'm at the 8:50 mark in the course and I'm attempting to test deploy to the Goerli testnet. After using command "yarn hardhat run scripts/deploy.js --network goerli" in my terminal, I get the following error.

**
Error HH8: There's one or more errors in your config file:

• Invalid value undefined for HardhatConfig.networks.goerli.url - Expected a value of type string.
• Invalid account: #0 for network: goerli - Expected string, received undefined

To learn more about Hardhat's configuration, please go to https://hardhat.org/config/
**

I went over the lesson involving the hardhat config network a few times but can't seem to figure out whats happening. My best guess is my hardhat config network installed @nomicfoundation/hardhat-toolbox but in the lesson has @nomiclabs/hardhat-waffle. hardhat waffle isn't downloaded in my package.json file. Everything in the lesson was working until i listed the default network, url, accounts etc.

thanks for your help! below i'll list what i have in my hardhat.config.js

[SandyTampaBay]

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

/** @type import('hardhat/config').HardhatUserConfig */

const GOERLI_RPC_URL = process.env.GOERLI_RPC_URL;
const PRIVATE_KEY = process.env.PRIVATE_KEY;

module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    goerli: {
      url: GOERLI_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 5,
    },
  },
  solidity: "0.8.9",
};

@SandyTampaBay This is a RPC URL issue, you should make sure it is correct and console.log it also in hardhat.config.js file to see the result

[alymurtazamemon]

@SandyTampaBay Make sure env package is installed.

[alymurtazamemon]

@SandyTampaBay And while learning, I will suggest you not use the hardhat toolbox plugin, and should use the same plugins and dependencies mentioned in the code repo. This will make your learning process smoother and you can later move to upgraded versions when you get familiar with everything.

hey @alymurtazamemon,

i tried to use console.log in hardhat.config.js and it turned up the same error i listed perviously. I reinstalled env package and double checked that both RPC_URL and Private key matched with each other. anything else i can try?

[SandyTampaBay]

also, what should i switch toolbox to? i thought that automatically came up when i installed something

I have the exact same error

@SandyTampaBay Please push to GitHub. I will look into it :)

[krakxn]

Is this resolved yet?

[SandyTampaBay]

hey sorry, I wasn't near my computer the last few days. I asked a follow up question below if you want to take a look.

[SandyTampaBay]

Thank you @krakxn

here it is. i accidentally left a portion of hardhat.config.js commented out right under module.exports. it seems that if i comment in any portion of that code i get the error i mentioned above.

@SandyTampaBay Now it is running, check this; I am going to push on your repo, check it there.

hey @alymurtazamemon,

sorry for the delay in answering. I'm still fairly new. how does this work? do i copy and paste the above to the command line? is it already uploaded and i just have to export it back to my Vs Code window? whats the next step for me?

[SandyTampaBay]

I attempted to figure out how to push the github repository to my vs studio. After doing that, and redoing my .env file, i got the following warning after using command yarn hardhat run scripts/deploy.js --network goerli

warning package.json: No license field
error Command "hardhat" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

not sure what do do from here. i understand that .gitignore blocked my original .env file so i redid that. do i have to install anything to get the packages you added in my package.json? Thanks
