Попытка получить свойство 'resource' необъекта в PaginatedResourceResponse. php после Laravel -update

Question

на самом деле я получаю эту ошибку после обновления Laravel с v7.5.1 до v7.6.2

"message": "Trying to get property 'resource' of non-object",
    "exception": "ErrorException",
    "file": "/home/vagrant/code/vendor/laravel/framework/src/Illuminate/Http/Resources/Json/PaginatedResourceResponse.php",
    "line": 29,
    "trace": [
        {
            "file": "/home/vagrant/code/vendor/laravel/framework/src/Illuminate/Http/Resources/Json/PaginatedResourceResponse.php",
            "line": 29,
            "function": "handleError",
            "class": "Illuminate\\Foundation\\Bootstrap\\HandleExceptions",
            "type": "->"
        },
        {
            "function": "Illuminate\\Http\\Resources\\Json\\{closure}",
            "class": "Illuminate\\Http\\Resources\\Json\\PaginatedResourceResponse",
            "type": "->"
        },
        {
            "file": "/home/vagrant/code/vendor/laravel/framework/src/Illuminate/Support/Collection.php",
            "line": 638,
            "function": "array_map"
        },
        {
            "file": "/home/vagrant/code/vendor/laravel/framework/src/Illuminate/Support/Traits/ForwardsCalls.php",
            "line": 23,
            "function": "map",
            "class": "Illuminate\\Support\\Collection",
            "type": "->"
        },

Вот что вызывает ошибку:

$products = Product::findMany($array)->paginate(10);
//dump($products);

/*Create ResourceCollection*/
return new ProductResourceCollection($products);

Дамп возвращается это:

}

Это ресурс:

public function toArray($request)
{
    return [
        'current_page'   => $this->resource->currentPage(),
        'first_page_url' => $this->resource->url(1),
        'from'           => $this->resource->firstItem(),
        'last_page'      => $this->resource->lastPage(),
        'last_page_url'  => $this->resource->url($this->lastPage()),
        'next_page_url'  => $this->resource->nextPageUrl(),
        'per_page'       => $this->resource->perPage(),
        'prev_page_url'  => $this->resource->previousPageUrl(),
        'to'             => $this->resource->lastItem(),
        'total'          => $this->resource->total(),
        'data'           => $this->collection->transform(function ($product
        ) {
            return [
                'id'                => $product->id,
                'title'             => $product->title,
                'category'          => $product->category,
            ];
        }),
    ];
}

Если я прокомментирую 'data'=> $this->collection->transform(function ($product) { ошибка не появляется ... Но ... Ну, тогда приложение не работа; -)

Мой вопрос

Итак, мой вопрос: неверен ли этот способ изменения данных и как я могу это исправить?

Answer 1

Проблема вызвана https://github.com/laravel/framework/pull/32296.

На данный момент я могу сделать что-то вроде

$this->collectResource($this->collection)
                ->transform(...)

, которое решает проблему.
