How do I change the the default lite-server port in Angular quickstart?

I just downloaded Angular 4 quickstart app and attempted to change the default lite-server port by adding "port": 8000 to bs-config.json as following:

{
  "server": {
    "port": 8000,
    "baseDir": "src",
    "routes": {
      "/node_modules": "node_modules"
    }
  }
}

When I npm start the app I see that bs-config.json is read OK, but lite-server still continues with the default port 3000

 >angular-quickstart@1.0.0 serve /Users/me/code/quickstart
[1] > lite-server -c=bs-config.json

What am I missing?

Based on the documentation, you should declare a port as a top level:

{
  "port": 8000,
  "server": {
    "baseDir": "src",
    "routes": {
      "/node_modules": "node_modules"
    }
  }
}
