Webpack 3.10.0 and babel-polyfill issue at runtime - reactjs

Question

I'm currently using Webpack 3.10.0 along with following babel packages.
"babel": "^6.23.0",
"babel-core": "^6.26.0",
"babel-loader": "^7.1.2",
"babel-polyfill": "^6.26.0",
"babel-preset-es2015": "~6.13.2",
"babel-preset-react": "~6.11.1",
My issue is, during runtime I get the following error on the browser console and the page doesn't load.
bundle.js:737 Uncaught Error: Cannot find module "babel-polyfill"
at webpackMissingModule (bundle.js:737)
at Object.<anonymous> (bundle.js:737)
at __webpack_require__ (bundle.js:679)
at bundle.js:725
at bundle.js:728
My webpack.config.js looks as below.
var webpack = require('webpack');
var path = require('path');
module.exports = {
devtool: 'eval-source-map',
entry: {
bundle: ['babel-polyfill', './Main.js'],
bundleIntegrated: ['babel-polyfill', './MainInt.js']
},
output: {
filename: '[name].js',
path: path.resolve(__dirname, '../assets/myproject')
},
target: 'web',
devServer: {
inline: true,
port: 3000,
proxy: {
'/myct/**': {
target: 'http://localhost:9000',
secure: false,
changeOrigin: true
}
}
},
plugins: [
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.HotModuleReplacementPlugin(),
],
resolve: {
extensions: ['.js', '.jsx'],
alias: {
config: path.join(__dirname, 'config/config.dev')
}
},
module: {
rules: [
{
test: /.(js|jsx)$/,
enforce: 'pre',
exclude: /node_modules/,
use: [
{
loader: "eslint-loader",
}
],
},
{
test: /\.(js|jsx)$/,
exclude: /(node_modules|__tests__)/,
loader: "babel-loader",
},
{
test: /\.css$/,
use: [
"style-loader",
"css-loader",
],
},
{
test: /\.less$/,
use: [
"style-loader",
"css-loader",
"less-loader",
],
},
{
test: /\.woff($|\?)|\.woff2($|\?)|\.ttf($|\?)|\.eot($|\?)|\.svg($|\?)/,
use: [
{
loader: "file-loader?name=../assets/mastering/fonts/[name].[ext]",
},
],
},
],
}
}
I have imported babel-polyfill into Main.js and MainInt.js files as instructed in https://babeljs.io/docs/usage/polyfill/ and I haven't used new webpack.optimize.ModuleConcatenationPlugin().
Any ideas on how to resolve this issue. Thanks in advance :)

I found the issue. Thank you everyone for your help.
Giving the full path in filename fixed the issue.
output: {
path: path.resolve(__dirname, '../assets/myproject'),
filename: '../assets/myproject/[name].js',
},
