From the “Response Interceptor” example it looks like the map() operator takes an error handler (err: any) => { ... } . However the Observable.map() doesn’t (http://reactivex.io/rxjs/class/es6/Observable.js~Observable.html#instance-method-map) and it looks like the handle() method returns a typical Observable (https://angular.io/api/common/http/HttpHandler).
