Hello everyone, when I am trying to use "yarn hardhat node" in the "hardhat-fund-me-fcc" folder, I get the following message:

I am not sure where the error comes from. Here is my 99-deploy-storage-fun.js content:

const { getNamedAccounts, deployments, network, ethers } = require("hardhat")
const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()

    log("----------------------------------------------------")
    log("Deploying FunWithStorage and waiting for confirmations...")
    const funWithStorage = await deploy("FunWithStorage", {
        from: deployer,
        args: [],
        log: true,
        // we need to wait if on a live network so we can verify properly
        waitConfirmations: network.config.blockConfirmations || 1,
    })

    log("Logging storage...")
    for (let i = 0; i < 10; i++) {
        log(
            `Location ${i}: ${await ethers.provider.getStorageAt(
                funWithStorage.address,
                i
            )}`
        )
    }
}

module.exports.tags = ["storage"]

I just cloned the files from github and deleted the comments. The rest is still the same.

[morismc]

Actually the error message popped up after calling ethers.provider.getStorageAt(funWithStorage.address,i).

When I call other functions on this address, there's no problem. E.g. I can get the contract balance. It just seems to be this method and I don't know why. Does anyone of you have any idea?

Odd... I am not able to reproduce. What OS are you using, windows, mac, linux?

For the time being, you could just go through the course and ignore (delete) the 99-deploy-storage-fun.js file.

Hi Patrick, thanks for your great content. I am running it on a Windows 11 environment but configured everything as you described in your first lessons.

[pramodhs2]

I was facing the same issue, but setting this solved

export NODE_OPTIONS=--openssl-legacy-provider

[boringslav]

I have the same issue. I tried @pramodhs2's solution export NODE_OPTIONS=--openssl-legacy-provider but after doing it node stopped working with the error: node: --openssl-legacy-provider is not allowed in NODE_OPTIONS. Had to unset with unset NODE_OPTIONS to be able to use node again.
I am using MacOS - idk if the issue is OS specific
