我是一名初學(xué)者 Web 開發(fā)人員 我正在嘗試編寫一個(gè)條件，該條件將根據(jù)用戶將發(fā)送的數(shù)據(jù)來滿足如果條件達(dá)到 100% 但其他條件會(huì)產(chǎn)生以下文本的錯(cuò)誤試圖獲取非對(duì)象的屬性“unique_id”如果有人知道如何解決這個(gè)問題，我將不勝感激這是我來自控制器的代碼public function checkRestorePassword(Request $request){    $result['success'] = false;    $rules = [        'unique_id' => 'required',    ];    $validation = Validator::make($request->all(), $rules);    if (empty($validation))    {        $result['error'] = "Enter the code that was sent to you by mail.";        return response()->json($result, 422);    }    $user = User::where('unique_id', $request->uniqueId)->first();    if ($user->unique_id === $request->uniqueId)    {        $result['success'] = 'Access to your personal account successfully restored. Please change your password.';        return response()->json($result, 200);    }    else    {        $result['success'] = false;        return response()->json($result, 422);    }}
