How do I use Data with Lazy in a job? I am getting Closure could not be serialized error.

So I have this data object:

<?php

namespace App\Data;

use ...;

class ReservationData extends Data
{
	public function __construct(
        ...
		public Lazy|BranchData $branch,
		public Lazy|CompanyData|null $company, // when I include a null here, I always get the property included in a response, which is not wanted.

		#[DataCollectionOf(PaymentTransactionData::class)]
		public Lazy|DataCollection|null $paymentTransactions,
        ...
	}

	public static function fromModel(Reservation $reservation): ReservationData
	{
		return new self(
			...
			branch: Lazy::whenLoaded("branch", $reservation, fn () => $reservation->branch),
			company: Lazy::whenLoaded("company", $reservation, fn () => $reservation->company),
			paymentTransactions: Lazy::whenLoaded("paymentTransactions", $reservation, fn () => PaymentTransactionData::collect($reservation->paymentTransactions)),
		    ...
		);
	}
}

When this is dispatched in a job, there's __sleep that serializes all of the properties including the Lazy, which have Closures in its body. This causes Exception: Serialization of 'Closure' is not allowed in /.../vendor/laravel/framework/src/Illuminate/Queue/Queue.php:160

I tried to convert it to a serializable format by doing

dispatch(new SomeJob(ReservationData::from(ReservationData::from($reservation)->toArray()))

Which kinda works if I have all the Lazy attributes marked as |null:

array:17 [
  "id" => 362
  "guid" => "6maae4is"
  "branch_id" => 1
  "datetime" => "2024-03-08T19:05:00+01:00"
  "persons" => 1
  "status" => "reserved"
  "created_at" => "2024-03-08T19:05:13+01:00"
  "branch" => null
  "company" => null
  "reservationNotes" => null
  "reservationStatusHistory" => null
  "reservationJournals" => null
  "timeslots" => null
  "paymentTransactions" => null
  "reservationSlots" => null
  "reservationSlotUsers" => null
  "reservationUsers" => null
]

But when I don't have the nullable types there, I get

  Could not create `App\Data\ReservationData`: the constructor requires 17 parameters, 16 given. Parameters given: id, ... branch, company, ... Parameters missing: paymentTransactions.

Is there a way to just serialize the job so I can continue using the Data object instead of passing the Model directly into the Job?

Thanks for your time <3
