Le type MIME ('text / html') n'est pas un type MIME de feuille de style pris en charge

J'ai essayé presque toutes les solutions pour le problème qui comprend. donner le type pour <link rel="stylesheet" href="./style.css" /> utilisation de app.use(express.static('public')) et bien d'autres mais il semble que je ne suis pas en mesure de trouver une solution pour ça.

index.js:

**Refused to apply style from 'http://localhost:9000/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.**

**Refused to execute script from 'http://localhost:9000/bundle.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.**

index.html:

"scripts": {
    "start": "webpack-dev-server --content-base dist/ --port 9000 --config webpack.config.js --watch --progress --inline --hot --history-api-fallback --mode development",
    "build": "cross-env NODE_ENV=production webpack --config webpack.config.js"
  },

webPack.config.js:

'use strict';
const webpack = require('webpack');

const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const CopyWebpackPlugin = require('copy-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin')

const plugins = [
  new CleanWebpackPlugin({
    root: __dirname,
    verbose: true,
    dry: false
  }),

Balise de script package.json:

<!DOCTYPE html>
<html>

<head>
  <meta http-equiv=X-UA-Compatible content="IE=edge,chrome=1">
  <meta name="viewport" content="width=device-width">

  <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
  <link rel="stylesheet" href="./style.css" />
</head>

<body>
  <div id="my-app"></div>
  <script type='text/javascript' src="./bundle.js"></script>
</body>

</html>

npm strat fonctionne bien, l'application fonctionne correctement, mais quand je fais npm run build, cela me donne l'erreur:

import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux'
import "./assets/styles/app.less";
import 'bootstrap/dist/js/bootstrap.js';
import App from './components/base/App';
import store from './store'

const provider =
  <Provider store={store}>
    <App />
  </Provider>

render(provider, document.getElementById('my-app'))

Dans la partie réseau, j'ai obtenu ce qui suit:

Ok response for : http://localhost:9000/bundle.js

cancled for : http://localhost:9000/style.css

Aidez-moi !!
