после установки пакета webpack-5-react-scripts выходит ошибка

В проекте используется create-react-app. После того, как сервере перестало билдиться с конфликтом webpack < 5, установила пакет webpack-5-react-scripts, и ошибка прошла, билдится и на сервере, и локально. Но теперь локально при старте приложения выходит ошибка:

Failed to compile.

Module not found: Error: Can't resolve 'os' in 'C:\github\other\web_support\app\chat-app\node_modules\local-ip-url'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need these module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add an alias 'resolve.alias: { "os": "os-browserify/browser" }'
        - install 'os-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.alias: { "os": false }

Вставляла предлагаемый resolve 'resolve.alias: { "os": "os-browserify/browser" }', вставляла 'resolve.alias: { "os": false }' в web.config.js, удаляла пакет 'os-browserify', но ошибка продолжает выходить. Пакет local-ip-url нужен. Подскажите, как заставить работать?

webpack.config.js

// import * as webpack from "webpack";

const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')

module.exports = {
    entry: {
       "web_chat": "./src/index.js",
       "web_chat.min": "./src/index.js",
    },
    module: {

            { test: /\.svg$/, use: 'svg-inline-loader' },
            { test: /\.css$/, use: [ 'style-loader', 'css-loader' ] },
            { test: /\.(js)$/, use: 'babel-loader' }
        ]
    },
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: '[name].js'
    },
    plugins: [
        new HtmlWebpackPlugin()
    ],
    mode: process.env.NODE_ENV === 'production' ? 'production' : 'development',
    resolve : { 
        alias: { "os": "os-browserify/browser" }
    }
}
