Ever since I updated my project from Beta6 to Beta7 I have been getting the following error.

**Error TS2339: Property ‘map’ does not exist on type ‘Observable’**

Yes, I have imported **“rxjs/add/operator/map”** and have also tried importing it in different ways like so:

```
import {Observable} from 'rxjs/Rx';
import 'rxjs/add/operator/map';
import 'rxjs/Rx';

```

Here is an example of the line that the error occurs.

`this.authHttp.get(url).map(res => res.json()); // via angular2-jwt`

Everything was working before I updated my project. Any help is appreciated.

Thanks!

@fiwinet I would recommend you to see if any of the answers of [this SO topic](http://stackoverflow.com/questions/37030963/angular-2-2-0-0-rc-1-property-map-does-not-exist-on-type-observableresponse) will help you - it seems that the issue might be caused by outdated TypeScript or a bug in the TypeScript services for VS.

Thanks @iignatov. That was the issue. When I opened up my VS there was an update there waiting for me. 🙂 So I installed it and the error cleared after that. I switched IDEs and so I haven’t used the VS for a few months now.

Thanks Again!
