Hardhat-Fund-Me "ReferenceError: RINKEBY_RPC_URL is not defined"

[ashrth]

Trying to run staging test but somehow node is not reading the .env file. The error I see is:
ReferenceError: RINKEBY_RPC_URL is not defined

Things I have tried:

• Reinstalling the dotenv package
• Adding the absolute path
• Removing all the white spaces
• Enclosing the URL is quotes
• Made sure my .env file's extension is correct and not .env.example
• Hard coding the url and private key, but then it throws another error saying "Invalid account it was expecting string but received number"

My hardhat-config file is:

require("@nomicfoundation/hardhat-toolbox")
require("hardhat-deploy")

require("@nomiclabs/hardhat-ethers")
const { getUsedIdentifiers } = require("typechain")
require("@nomicfoundation/hardhat-toolbox")
require("hardhat-gas-reporter")
// require("@nomiclabs/hardhat-waffle")
// require('hardhat/config').HardhatUserConfig

// require("@nomiclabs/hardhat-etherscan")
// require("solidity-coverage")

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

module.exports = {
    solidity: {
        compilers: [{ version: "0.8.8" }, { version: "0.6.6" }],
    },
    defaultNetwork: "hardhat",
    networks: {
        rinkeby: {
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 4,
            blockConfirmations: 6,
        },
    },
    gasReporter: {
        enabled: true,
        outputFile: "gas-report.txt",
        noColors: true,
        currency: "USD",
        coinmarketcap: COINMARKETCAP_API_KEY,
        token: "ETH",
    },
    etherscan: {
        apiKey: ETHERSCAN_API_KEY,
    },
    namedAccounts: {
        deployer: {
            default: 0,
        },
        player: {
            default: 1,
        },
    },
}

I have been looking at StackOverFlow and applying the solutions from there, but no luck so far, also please tell why is it not reading the env file?

@ashrth I think you have missed this in hardhat file require("dotenv").config();

[RoboCrypter]

@ashrth : alright let me check

[alymurtazamemon]

@ashrth correct it!

- require("dotenv").config
+ require("dotenv").config()

[ashrth]

@alymurtazamemon It worked, Thank you so much mate.

[RoboCrypter]

@ashrth : we were all telling you that same thing, But nice to finally resolving your issue.

[ashrth]

@abossofmyself Yes my bad, I had mentioned it but I was missing ( ) these, also I had to initialize the env variables again in order to make it work, so this alone did not work.

Hey @ashrth you haven't included require("dotenv").config(); and I've seen you haven't initialized RINKEBY_RPC_URL too. You should probably compare with the lesson repo and see how you can import them from your .env file
It is probably something like this const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL

[ashrth]

@abossofmyself I have tried both, quotes and without quotes and get the same error....

[othaime-en]

Push you code to github and leave a link here. I'll look into it.
