My webpack bundle isn't sent with Express app.get('/*')

I'am have a bundle.js file that is attached with my index.html. I use a dynamic path at first :

app.get('/*', function(req, res) {

      res.sendFile(path.join(__dirname + '/src/index.html'));

  });

When I connect to localhost:8080/something, the html is sent but the div where the bundle is supposed to be displayed is empty.

But when I change the path to static one (like app.get('/',..)) and connect to localhost:8080/, the bundle is displayed.

How can I make this work with a dynamic path?
