Page is loaded however no content is shown - Angular CLI project

### A descriptive title
I'm creating a simple project using Angular-CLI, and it was working fine (when I run ng serve, the browser can load the page). However it was not detecting file changes, then I installed lite-server as I saw it being used on Angular Quicklaunch. The problem is that it runs fine, but nothing appears in the page content area.

### Bug repro steps
The code and Dockerfile is available at https://github.com/julianonunes/angular_simple, I'm creating the project and running from a Docker container based on node:7.10 image.

1. Created the project using Angular CLI (ng new)
2. Added ngx-bootstrap package
3. Run npm install
4. Run npm start

### Environment
- `lite-server` version: 2.3.0 (just installed locally)
- `nodejs` version: v7.10.0
- `npm` version: 4.2.0
- OS type/version: Debian:jessie
