Why does the route with id, react/webpack not work?

Question

JavaScript

Good afternoon! Please tell me what is the problem?
Route type not working

<Route
                        path="/some/:someId"
                        component={SomePage}
                      />

error

http://localhost:3000/some/bundle.js net::ERR_ABORTED 404 (Not Found)

Project on react/redux/typescript/webpack The
question is, what needs to be added to webpack or .babelrc to make it work?

I would be very grateful for your help!
