Actual behavior After Upgrading from 7.5.2 to 7.5.3 the following error message is displayed in console: Cannot read property 'classList' of undefined at DefaultDomRenderer2.push../node_modules/@angular/platform-browser/fesm5/platform-browser.js.DefaultDomRenderer2.addClass (platform-browser.js:1102) at BaseAnimationRenderer.push../node_modules/@angular/platform-browser/fesm5/animations.js.BaseAnimationRenderer.addClass (animations.js:239) at DebugRenderer2.push../node_modules/@angular/core/fesm5/core.js.DebugRenderer2.addClass (core.js:28546) at CarouselComponent.push../node_modules/ng-uikit-pro-standard/fesm5/ng-uikit-pro-standard.js.CarouselComponent.ngAfterViewInit (ng-uikit-pro-standard.js:1410)

i realized the code which cause this problem is: (carousel.component.ts line: 145)

if (this.isControls) {
  this.carouselIndicators = this.el.nativeElement.querySelectorAll('.carousel-indicators > li');
  if (this.carouselIndicators.length && this.activeSlideIndex) {
    this.renderer.addClass(this.carouselIndicators[this.activeSlideIndex], 'active');
  } else {
    this.renderer.addClass(this.carouselIndicators[0], 'active');
  }
}
