How to retrieve products from database laravel

I'm trying to display all products of specific user from database but I get an error Call to a member function count() on null" how can I display the products?

Controller

public function favouritelist(Request $request)

{
    $products = $request->user()->favouriteProducts()->first();
    return view('front.wishlist', compact('products'));
}

User.php

 public function favouriteProducts(){
    return $this->morphedByMany(Product::class,'favouriteable')
    ->withPivot(['created_at'])->orderBy('pivot_created_at', 'desc');
 }
