Need BrowserAnimationsModule in Angular but gives error in Universal

Hi I am using Angular that uses the BrowserAnimationsModule. But in the universal server side it gives the error "document is not defined".

Because Universal doesn't support BrowserAnimationsModule I need a way to make the server ignore BrowserAnimationsModule and replace it with NoopAnimationsModule.

This is what I have right now but it's not working. Any other methods are welcome too.

let imports = [
    BrowserModule.withServerTransition({appId: 'ang4-seo'}),
    FormsModule,
    HttpModule,
    routes
];

if(isPlatformBrowser(PLATFORM_ID)){
    imports.push(BrowserAnimationsModule);
}

@NgModule({
    imports: imports,

Are there any ways to solve this?
