我有一个函数，它返回staff和相关属性，如下所示

foreach ($merchant_user_ac->staffs->sortByDesc('id') as $staff) {
  $wage = Staff::find($staff->id)->totalCommissions($start_date, $end_date);

  $payments = StaffPayment::where('merchant_id', AH::cMiD())
    ->where('user_id', $staff->id)
    ->when(!empty($start_date) && !empty($end_date), function ($q) use (
      $start_date,
      $end_date
    ) {
      $q->whereBetween(\DB::raw('date(payment_date)'), [
        $start_date,
        $end_date,
      ]);
    })
    ->sum('amount');

  $balance_owed = $wage - $payments;

  $transactions->add([
    'id' => $staff->id,
    'name' => $staff->name,
    'profilephoto' => $staff->profilephoto,
    'wage' => $wage,
    'payments' => $payments,
    'salary' => $staff->salary,
    'rent' => $staff->rent,
    'balance_owed' => $balance_owed + $staff->salary - $staff->rent,
  ]);
}

$merchant_staffs = collect(json_decode(json_encode($transactions), false));
$merchant_staffs = $merchant_staffs->paginate(10);
return response()->json($merchant_staffs);

在结果中，第一页正常，但后续页的数据类型与第一页不同，显示数据成为一个问题。

数据键具有不同的数据类型。我已尝试在foreach循环之前分页，但响应没有分页链接。我已尝试在收集数据时添加->toArray()方法，但存在不同类型的相同问题。
如何在所有分页链接中返回相同的数据？
返回的数据如下
