 let ethUsdPriceFeedAddress
    if (chainId == 31337) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    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}`)

@devkumar4 Check this line

ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]

Either ethUsdPriceFeed spelling could be wrong or here chainId is undefined. Make sure both of these things.
