Hi guys, I was trying to customize the video’s css style by building openvidu-library-angular from the source code, following [this guide](https://docs.openvidu.io/en/2.15.0/developing/#compiling-openvidu-angular-library) on Mac. My project made use of openvidu-library-angular _stream.component_. It worked fine when I manually add the newly built local package **openvidu-angular-2.15-0.tgz** to my project folder then npm install it. However, it gave me this error when I **ng serve**. **ERROR in ./src/app/app.module.ngfactory.js 181:3876-3909** **"export ‘OverlayOutsideClickDispatcher’ (imported as ‘i63’) was not found in '@angular/cdk/overlay’** I checked for OverlayOutsideClickDispatcher in both my project and the original openvidu-call file, but there was none of it. However, it seemed to be from the local openvidu-angular-2.15.0.tgz package. In my project’s **package-lock.json** there is an existing @angular/cdk 9.2.4 inside openvidu-angular’s dependencies. On the other hand, in the openvidu-call file’s package-lock.json there is @angular/cdk 10.1.3. I don’t know whether the difference in version could be the issue. If so, how can I resolve this? I would very much appreciate any help! Thanks in advance. ---

Hello @Katie_Le, Could you write the steps to reproduce this problem? I think you’re using the master branch of OpenVidu Call rigth? ---

UPDATED Please, uses the official release of openvidu-angular. We’re daily improving the source code in each repositories. And some tutorials need some changes to make it wirk with the new updates. Cheers ---

Hi! Yes I’m on master, and I’ve just downloaded the openvidu-call package 3 days ago. All of the other openvidu source code I’m using are of version 2.15.0. My app runs fine with just the official openvidu-angular package installed, but not with the local tgz one. This is what I did before the problem occurred: • Bring the code in **app.component.ts/htm/css** from openvidu-library-angular to my app, changing its name to stream.component and configuring it in my app.module.ts and app-routing.module.ts • Paste the _Jquery_ script, the _global variable_ and _Material icons font_ in my **index.html** • Go to openvidu-call and edit some css, then build that into openvidu-angular and pack it as a local tgz file • Move the new tgz package into my app’s folder, then install it here • Encounter the issue when I **ng serve** the app on localhost Hope these provide you with some more details! Thank you for your help:) ---
