Boostraped components are defined in the bootstrap property of an @NgModule decorator or as the first parameter of boopstrapApplication for standalone components.
This error happens when Angular tries to boostrap one of these components but cannot find its corresponing node in the DOM.
This issue occurs when the selector mismatches the tag
@Component({
selector: 'my-app',
...
})
class AppComponent {} <html>
<app-root></app-root> <!-- Doesn't match the selector -->
</html> Replace the tag with the correct one:
<html>
<my-app></my-app> <!-- OK -->
</html>
