hey, were you able to resolve this error?

[krakxn]

Which network are you running on?

[aaankeet]

deploy-fund-me.js

const { getNamedAccounts, deployments, network } = 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()
    const chainId = network.config.chainId

let ethUsdPriceFeedAddress
if (chainId == 4) {
    const ethUsdAggregator = await deployments.get("MockV3Aggregator")
    ethUsdPriceFeedAddress = ethUsdAggregator.address
} else {
    ethUsdPriceFeedAddress = networkConfig[chainId]["priceFeedAddress"]
}
log("----------------------------------------------------")
log("Deploying FundMe and waiting for confirmations...")
const fundMe = await deploy("FundMe", {
    from: deployer,
    args: [ethUsdPriceFeedAddress],
    log: true,
    // we need to wait if on a live network so we can verify properly
    waitConfirmations: network.config.blockConfirmations || 1,
})
log(`FundMe deployed at ${fundMe.address}`)

if (
    !developmentChains.includes(network.name) &&
    process.env.ETHERSCAN_API_KEY
) {
    await verify(fundMe.address, [ethUsdPriceFeedAddress])
}
}

MockV3Aggregator.sol

//SPDX-License-Identifier: MIT
pragma solidity ^0.6.0;

import "@chainlink/contracts/src/v0.6/tests/MockV3Aggregator.sol";

[krakxn]

Is the file name of your test contract equivalent to MockV3Aggregator? Can't diagnose any problem besides that.

[aaankeet]

yes everything is fine idk what is the actual problem behind this i think i am gonna trash this whole and start a new one
hope that helps

[krakxn]

Yeah, that is a very weird error because even the code seems to be fine (unless I made a careless mistake, unlikely) - didn't encounter it once answering discussions

[krakxn]

Quoting from StackOverflow, let me know if it helps.

Here are two options now -

1. Try to uninstall Node.js version 17+ and reinstall the Node.js version 16+

You can re install the current LTS node js version from their official site. or more specific downloads from here;

You can use NVM (Node Version Manager)

Linux and Mac users can use this nvm package - https://github.com/nvm-sh/nvm
Windows users can use this nvm package - https://github.com/coreybutler/nvm-windows

2. Open terminal and paste these as described :

Linux & Mac OS (windows git bash)-

export NODE_OPTIONS=--openssl-legacy-provider
Windows command prompt-

set NODE_OPTIONS=--openssl-legacy-provider
Reference link.

[pheuberger]

If after setting the NODE_OPTIONS like mentioned above your node process complains with node: --openssl-legacy-provider is not allowed in NODE_OPTIONS then maybe your distribution doesn't enable legacy SSL support out of the box. I'm running Fedora 36 and had to edit /etc/ssl/openssl.cnf. See https://stackoverflow.com/questions/72866798/node-openssl-legacy-provider-is-not-allowed-in-node-options

Same problem here but comes from Lesson 15 When use command yarn run moralis:cloud
Solution
downgrades from node v18.6.0 to LTS which is v16.16.0. and install yarn again, If not found yarn.

nvm use --lts
npm install -g yarn
