An unexpected error occurred

[Flopicek]

I am having problem with deploying a contract on a goerli testnet. Could anyone help?

const { networkConfig, developmentChain } = require("../helper-hardhat-config")
const { network } = require("hardhat")
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 (developmentChain.includes(network.name)) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }

    const args = [ethUsdPriceFeedAddress]
    const fundMe = await deploy("FundMe", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })
    if (
        !developmentChain.includes(network.name) &&
        process.env.ETHERSCAN_API_KEY
    ) {
        await verify(fundMe.address, args)
    }
    log("---------------------------------------------------")
}

module.exports.tags = ["all", "fundme"]

It is giving me this kind of error

I think there is something wrong with the ... ethUsdPriceFeed ... as it is written in Error description ... but I cannot find a solution ...

Found it ... I did have a wrong chainID in my helper-hardhat-config.js file ... I had 4 instead of 5.
