Problem description

Hi everyone,

I have updated Filament v2 to v3 and I am stuck on a problem "View [1] not found".

I am using this code below :

{
    protected static string $relationship = 'products';

    protected static ?string $recordTitleAttribute = 'name';

    public function form(Form $form): Form
    {
        return ProductResource::form($form);
    }

    public function table(Table $table): Table
    {
        return ProductResource::table($table)
            ->headerActions([
                Tables\Actions\CreateAction::make(),
            ])
            ->actions([
                Tables\Actions\EditAction::make(),
                Tables\Actions\DeleteAction::make(),
            ])
            ->bulkActions([
                Tables\Actions\DeleteBulkAction::make(),
            ]);
    }
}```

### Expected behavior

I need to display relationship of a model (Products attached to Adverts) in a list / table (see Filament v2 result in attachment).

### Steps to reproduce

Using `getRelation()` in Resource file : 

public static function getRelations(): array
{
return [
AdvertProductRelationManager::class
];
}

Hey @Arachnos! We're sorry to hear that you've hit this issue. 💛

However, it looks like you forgot to fill in the reproduction repository URL. Can you edit your original post and then we'll look at your issue?

We need a public GitHub repository which contains a Laravel app with the minimal amount of Filament code to reproduce the problem. Please do not link to your actual project, what we need instead is a minimal reproduction in a fresh project without any unnecessary code. This means it doesn't matter if your real project is private / confidential, since we want a link to a separate, isolated reproduction. That would allow us to download it and review your bug much easier, so it can be fixed quicker. Please make sure to include a database seeder with everything we need to set the app up quickly.
