我有一個 Livewire 組件：  class Cards extends Component  {   use WithFileUploads;   public $question;   public $answer;   public $questionImage;   public $questionImageOrigin;   public $answerImage;   public $answerImageOrigin;   public $questionAudio;   public $questionAudioOrigin;   public $answerAudio;   public $answerAudioOrigin;   public function render()   {       return view('livewire.cards');   }現在我想創建并驗證一張卡：   public function createCard(){    $this->validate([        'answerImage' => 'nullable|image|max:3000',        'questionImage' => 'nullable|image|max:3000',        'question' => 'required_without_all: questionImage, questionAudio',        'answer' => 'required_without: answerImage, answerAudio',        'questionAudio' => 'nullable|file|mimeTypes:audio/mpeg|max:3000',        'answerAudio' => 'nullable|file|mimeTypes:audio/mpeg|max:3000'    ]);但這是行不通的。當我插入某些內容（圖像或音頻）時，出現錯誤：The answer field is required when answer image / answer audio is not present.所以 - 我想這是行不通的。還是我錯了？也許我必須使用另一種語法？但我在文檔中沒有找到任何內容。請幫忙。
