Navigate to specific page defined on model when Item is Tapped - events

Question

I'm trying to make a custom home page where pages are listed on an Horizontal scroll view as "Services" so each one of them should navigate to a different Page.
I have a view like this:
<controls:HorizontalScrollView HeightRequest="160"
Orientation="Horizontal"
ItemsSource="{Binding OwnerServicesList}"
x:Name="OwnerServicesSlider"
ItemSelected="OwnerServicesSlider_ItemSelected">
<controls:HorizontalScrollView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Margin="10,0,5,0" WidthRequest="100" HeightRequest="100">
<Image HorizontalOptions="Start" Source="{Binding ImgUrl}" WidthRequest="100" HeightRequest="100" />
<Label Style="{StaticResource BoldLabel}" HorizontalTextAlignment="Center" FontSize="13" LineBreakMode="TailTruncation" Text="{Binding Name}" TextColor="Black"/>
</StackLayout>
</ViewCell>
</DataTemplate>
Im using a custom made controller for a Horizontal Scroll view that works like a listview, every item on tap raises a ItemTappedEventArgs event.
Inside my model i´ve declared a public Page Page { get; set; } for each object in the scroll view.
What im trying to do is recover the tapped element and recover the Page stored in it so that I can Navigate to that specific page.
So far I have something like this:
private void OwnerServicesSlider_ItemSelected(object sender, ItemTappedEventArgs e)
{
var service = OwnerServicesSlider.SelectedItem as Services;
Navigation.PushAsync(service.Page);
}
It shows no errors but when I run it I get a
InvalidOperationException: 'Page must not already have a parent.
Any hint will be appreciated!

as Jason said,maybe the page you would push which is exist in thecurren navigation structure,there is a workaround ,before you push the page :
private void OwnerServicesSlider_ItemSelected(object sender, ItemTappedEventArgs e)
{
var service = OwnerServicesSlider.SelectedItem as Services;
service.Page.Parent = null;
Navigation.PushAsync(service.Page);
}
