Good day !

Since I updated my project to **4.0.0-beta.12** I have been getting the following error.

> ERROR in src/app/pages/deactivate-device/deactivate-device.ts(171,53): error TS2  
> 339: Property ‘timeout’ does not exist on type ‘Observable \<Response’.

I add to page.

> import {timeout} from ‘rxjs/operators’;

I use.

> this.http.post(this.actions, data).timeout(40000).subscribe(serverData =\> {
> 
> }, err =\> { }

ionic info:

I don’t think it’s related to the upgrade to Ionic but rather to a not correct use of rxjs timeout as of rxjs 6

Here an example of timeout pipe:

```
import {timeout} from 'rxjs/operators';

this.anObservable()
   .pipe(
      timeout(4000)
   ).subscribe((result: any) => {
      console.log('Cool');
   }, (err: any) => {
      console.log('Not cool');
  });
```

You may want to either downgrade to rxjs version 5 (perhaps 5.5.12), or update your code for version 6. I had a similar issue when I upgraded to version 6, 'cos I didn’t realize that there was a lot of changes in 6, so I had to downgrade to 5.5.12.

This link might help [https://www.academind.com/learn/javascript/rxjs-6-what-changed/](https://www.academind.com/learn/javascript/rxjs-6-what-changed/)

Good luck.

</div>

and `@angular/...`?  
maybe something went bad during the installation? have you try to remove `node_modules` and reinstall all the libs?

[obinnae](https://forum.ionicframework.com/u/obinnae),thanks a lot.

[reedrichards](https://forum.ionicframework.com/u/reedrichards), I reinstalled node\_modules… it dose not help.

</div>

that’s super weird, you are using Ionic v4 right?

did you do a clean/force install of the dependencies?

```
rm -r node_modules
rm package-lock.json
npm install
```
