I have the following route defined in my web.php, to return a list of my Excepcion records in DB:

```
use App\Excepcion;
use App\Http\Resources\Excepcion as ExcepcionResource;
(...)
Route::get('/list/excepciones', function () {
    return ExcepcionResource::collection(Excepcion::where('active', '1'));
});

```

But I'm getting the following server error:

```
Call to undefined method Illuminate\Database\Eloquent\Builder::mapInto()

```

If I change it to `Excepcion::all()` it works just fine. So, I'm not sure why I cannot use a where condition nor a scope. How can I filter the results here?
