Cannot retrieve() cause of failing instantiate Enum

[lfleigl]

I work on the event-sourcing book and get an error by AccountAggregateRoot::retrieve($account->uuid) cause of using an Enum for the AccountType - or "better" => "Cannot instantiate enum App\Domain\Account\Enums\AccountType"

namespace App\Domain\Account\Enums;

enum AccountType: string
{
    case CUSTOMER = 'customer';
    case SUPPLIER = 'supplier';
    case CONSUMER = 'consumer';
}

use App\Domain\Account\Enums\AccountType;

class AccountData
{
    public function __construct(
        public AccountType $accountType,
        public string $internalNumber,
        public string $externalNumber,
        public string $company,
        public string $salutation,
        public ?string $name,
    ) {
    }
}

{
    "uuid": "d3ff798b-cdde-44ec-be23-8d64aaa8684f",
    "accountData": {
        "accountType": {
            "name": "CUSTOMER",
            "value": "customer"
        },
        "internalNumber": "12345",
        "externalNumber": "98765",
        "company": "Your Company",
        "salutation": "Firma",
        "name": null
    },
    "createdAt": "2022-07-29T11:11:41+02:00"
}

If I'll change the structure of AccountData from AccountType to a simple string - it works perfect.

I believe there is a bug in the package, I experienced this and I had to change the type-hinted enum to a simple string instead, and pass its string around instead of the enum type hint.

Should be enough to add

        Symfony\Component\Serializer\Normalizer\BackedEnumNormalizer::class,

to event_normalizers in config/event-sourcing.php.

I'm getting same error

Cannot instantiate enum App\Enums\Commission\CommissionSubtype

'event_properties`

{"subtype": {"name": "NEW", "value": "NEW"}, "attributes": []}

'event_normalizers' => [
  Spatie\EventSourcing\Support\CarbonNormalizer::class,
  Spatie\EventSourcing\Support\ModelIdentifierNormalizer::class,
  Symfony\Component\Serializer\Normalizer\DateTimeNormalizer::class,
  Symfony\Component\Serializer\Normalizer\ArrayDenormalizer::class,
  Spatie\EventSourcing\Support\ObjectNormalizer::class,
  Symfony\Component\Serializer\Normalizer\BackedEnumNormalizer::class,
],

normalizer doesn't work

Moved BackedEnumNormalizer to the top, and it started to work :D

'event_normalizers' => [
    Symfony\Component\Serializer\Normalizer\BackedEnumNormalizer::class,
    Spatie\EventSourcing\Support\CarbonNormalizer::class,
    Spatie\EventSourcing\Support\ModelIdentifierNormalizer::class,
    Symfony\Component\Serializer\Normalizer\DateTimeNormalizer::class,
    Symfony\Component\Serializer\Normalizer\ArrayDenormalizer::class,
    Spatie\EventSourcing\Support\ObjectNormalizer::class,
],
