Entrypoint undefined = index.html using HtmlWebpackPlugin

Question

I'm using Webpack 4 and I'm creating the config file, when trying to use the HtmlWebpackPlugin it got this on the console: Entrypoint undefined = index.html, it opens the browser and the HTML does appear but I'm getting this weird message on the console, how to solve this?

That is how my config file looks like:

'use strict'

const webpack = require('webpack')
const { join, resolve } = require('path')

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

module.exports = {
  mode: 'development', // dev
  devtool: 'cheap-module-eval-source-map', // dev
  entry: join(__dirname, 'src', 'index.js'),
  output: {
    filename: 'bundle.js',
    path: resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader'
      }
    ]
  },
  resolve: {
    extensions: ['*', '.js', '.jsx']
  },
  devServer: {
    contentBase: resolve(__dirname, 'build')
  },
  plugins: [
    new webpack.ProgressPlugin(),
    new HtmlWebpackPlugin({
      template: join(__dirname, 'public', 'index.html')
    }),

    new webpack.HotModuleReplacementPlugin(), // dev
    new webpack.NoEmitOnErrorsPlugin() // dev
  ]
}

Try this; you might be making wrong template path :

 new HtmlWebpackPlugin({
        template: resolve(__dirname, 'src/public', 'index.html'),
        filename: './index.html'
      }),

If public is in src folder this should work It's my assumption. Let me know if the issue still persists.
