404 после развертывания углового приложения на сервере Heroku

Question

Я пытаюсь развернуть угловое приложение на сервере Heroku следующим способом.https://medium.com/@hellotunmbi/how-to-deploy-angular-application-to-heroku-1d56e09c5147

Если у кого-то есть идеи по этому поводу, пожалуйста, помогите мне, так как я пытаюсь найти корень этой ошибки.Заранее спасибо

Приложение выдает мне сообщение «ошибка не найдена», и ошибка консоли Не удалось загрузить ресурс: сервер ответил с состоянием 404 (не найдено).

Это приложение отлично работает на моем локальном сервере.

server.js

//Install express server
const express = require('express');
const path = require('path');

const app = express();

// Serve only the static files form the dist directory
app.use(express.static('./dist/beautyStyle'));

app.get('/*', function(req,res) {
    res.sendFile(path.join(__dirname,'/dist/beautyStyle/index.html'));
});

// Start the app by listening on the default Heroku port
app.listen(process.env.PORT || 8080);
