Chunk not available for synchronous require yet, Module parse failed: Unexpected character

Hi!

My server side rendering via hypernova is smooth and chunk reporting (stats) is fine. But as soon as client builds (chunks) are loaded, one of my route specific component collapse all its rendering and show `Error: export not found` instead. Rest of common things appear and render on its place in perfect order.

**Here is the warning I traced in browser console about synchronous require failure:**

> chunk not available for synchronous require yet: h4yQ: Module parse failed: Unexpected character '' (1:7)
You may need an appropriate loader to handle this file type.

**A fallback call for `requireAsync` also gets fails with this call stack:**

**Here are my webpack configs for client chunking**
```javascript
const path = require('path');
const webpack = require('webpack');
const aliases = require('./aliases');
const getClientEnvironment = require('./env');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-3-webpack-plugin');

const env = getClientEnvironment('');
const cssFilename = 'static/css/[name].[contenthash:8].css';
const extractSass = new ExtractTextPlugin({
filename: cssFilename,
});

// the path(s) that should be cleaned
const pathsToClean = ['build/static'];

// the clean options to use
const cleanOptions = {
root: path.resolve(__dirname, '../'),
verbose: true,
dry: false,
};

module.exports = {
name: 'client',
target: 'web',
devtool: 'source-map',
entry: path.resolve(__dirname, '../src/index.js'),
output: {
// libraryTarget: 'commonjs',
filename: 'static/js/[name].[chunkHash:8].js',

}),
},
],
},
// mode: 'development',
resolve: {

plugins: [
extractSass,
new webpack.DefinePlugin(env.stringified),

new webpack.HashedModuleIdsPlugin(), // not needed for strategy to work (just good practice)
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
minChunks(module) {
// this assumes your vendor imports exist in the node_modules directory
return module.context && module.context.includes('node_modules');
},
}),
new webpack.optimize.CommonsChunkPlugin({
name: 'bootstrap',
minChunks: Infinity,
}),
new webpack.optimize.CommonsChunkPlugin({
children: true,
minChunks: 3,

new CleanWebpackPlugin(pathsToClean, cleanOptions),

};
```

What are we missing here? How can we locate the location that is point of failure?
