How to catch exception correctly from http.request()?
<p><strong>Part of my code:</strong>
</p>

<pre><code>import {Injectable} from 'angular2/core';
import {Http, Headers, Request, Response} from 'angular2/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/add/operator/map';

@Injectable()
export class myClass {

  constructor(protected http: Http) {}

  public myMethod() {
    let request = new Request({
      method: "GET",
      url: "http://my_url"
    });

    return this.http.request(request)
      .map(res =&gt; res.json())
      .catch(this.handleError); // Trouble line. 
                                // Without this line code works perfectly.
  }

  public handleError(error: Response) {
    console.error(error);
    return Observable.throw(error.json().error || 'Server error');
  }

}
</code></pre>

<p><code>myMethod()</code> produces exception in console of browser:</p>

<blockquote>
  <p>ORIGINAL EXCEPTION: TypeError: this.http.request(...).map(...).catch is not a function</p>
</blockquote>
