lesson 14 Error:TypeError: str.charCodeAt is not a function

[highHumann]

Please help I'm getting this error:TypeError: str.charCodeAt is not a function

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

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

    const chainId = network.config.chainId
    let ethUsdPriceFeedAddress

    if (developmentChains.includes(network.name)) {
        const EthUsdAggregator = await ethers.getContract("MockV3Aggregator")
        ethUsdPriceFeedAddress = EthUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId].ethUsdPriceFeed
    }
    log("-----------------")
//IT IS HOWING AN ERROR WHILE PROCESSING THESE TWO LINES
    const lowSVG = await fs.readFileSync("./images/dynamicNft/frown.svg", { encoding: "utf8" })
    const highSVG = await fs.readFileSync("./images/dynamicNft/happy.svg", { encoded: "utf8" })
    args = [ethUsdPriceFeedAddress, lowSVG, highSVG]
    const dynamicSvgNft = await deploy("DynamicSvgNft", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })

    if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        log("Verifying...")
        await verify(dynamicSvgNft.address, args)
    }
}

module.exports.tags = ["all", "dynamicsvg", "main"]

I have done the compilation process everything is working but I'm getting an error while processing deploy-dynamic-svg-nft.js

Make sure the SVG file is correct.
when you open it in text editor, would be like this:

<?xml version="1.0" standalone="no"?>
<svg width="1024px" height="1024px" viewBox="0 0 .....

[highHumann]

yes it does

[alfaqi]

remove await keyword

const lowSVG = await fs.readFileSync("./images/dynamicNft/frown.svg", { encoding: "utf8" })
const highSVG = await fs.readFileSync("./images/dynamicNft/happy.svg", { encoded: "utf8" })

been like this

const lowSVG = fs.readFileSync("./images/dynamicNft/frown.svg", { encoding: "utf8" })
const highSVG = fs.readFileSync("./images/dynamicNft/happy.svg", { encoded: "utf8" })

[highHumann]

I have removed await still it is showing this error

@highHumann
Its Suppose to be encoding for both of the SVG.
typo in highSVG its encoding:"utf8" not encoded

const lowSVG = fs.readFileSync("./images/dynamicNft/frown.svg", { encoding: "utf8" })
const highSVG = fs.readFileSync("./images/dynamicNft/happy.svg", { encoding: "utf8" })

[highHumann]

thanks a lot
