[Heroku][Angular] "Template parse errors" when I deploy my app

When I deploy my application with "express" on heroku I have errors of this type:

Uncaught Error: Template parse errors:

Locally with "npm start" I have no error.

I think I have a configuration problem that does not include some html syntax.

app.js

var express = require('express');
var basicAuth = require('basic-auth-connect');

var app = express();

app.use(basicAuth('xxxx', 'xxxxxxxx'));
app.use(express.static('face-recognition/public'));
app.use("/public", express.static('public'));

var port = process.env.PORT || 3000;

app.listen(port, function () {
  console.log(`Example app listening on port ${port} !`);
});

webpack-config

var helpers = require('./config/helpers');

module.exports = {
    entry: "./app/main.ts",
    output: {
        path: helpers.root('public/js'),
        filename: "bundle.js",
        publicPath: '/js/'
    },
    resolve: {
      extensions: ['.ts', '.js']
    },

    module: {
      rules: [
        {
          test: /\.ts$/,
          loaders: [
            {
              loader: 'awesome-typescript-loader',
              options: { configFileName: helpers.root('app', 'tsconfig.json') }
            },
            {
              loader: 'angular2-template-loader'
            }
          ]
        },
        {
          test: /\.html$/,
          loader: 'html-loader'
        },
        {
          test: /\.js$/,
          exclude: /node_modules/,
          loader: 'babel'
        }
      ]
    },
    devServer: {
        historyApiFallback: true
    }
};
