In this example, ``ICalculator`` and ``ITaxCalculator`` are default interfaces of ``TaxCalculator``, but ``ICanCalculate`` is not.

When the `RestService` is used, all HTTP errors are reported to the [`HttpErrorReporterService`](./HTTP-Error-Reporter-Service), and then `ErrorHandler`, a service exposed by the `@abp/ng.theme.shared` package automatically handles the errors.
### Error Configurations
ABP offers a configurations for errors handling like below
```ts
import { ThemeSharedModule } from '@abp/ng.theme.shared';
import { MyCustomRouteErrorComponent } from './my-custom-route.component';
@NgModule({
imports: [
ThemeSharedModule.forRoot({
httpErrorConfig: {
skipHandledErrorCodes: [403],
errorScreen: {
forWhichErrors: [404],
component: CustomErrorComponent,
hideCloseIcon: false
}
}
}),
...
],
})
export class AppModule {}
```
- `ErrorScreenErrorCodes` the error codes that you can pass to `skipHandledErrorCodes` and `forWhichErrors`.
- `skipHandledErrorCodes` the error codes those you don't want to handle it.
- `errorScreen` the screen that you want to show when a route error occurs.
- `component` component that you want to show.
- `forWhichErrors` same as `ErrorScreenErrorCodes`
- `hideCloseIcon` hides close icon in default ABP component.
