ErrorResource missing title and details in JSON+LD response

[derTuca]

API Platform version(s) affected: 4.0.16

Description
I have created this ErrorResource class.

<?php
// api/src/ApiResource/OtpAlreadyRequestedError.php

namespace App\ApiResource;
use ApiPlatform\Metadata\ErrorResource;
use ApiPlatform\Metadata\Exception\ProblemExceptionInterface;

#[ErrorResource]
class OtpAlreadyRequestedError extends \Exception implements ProblemExceptionInterface
{
    public function getType(): string
    {
        return '/errors/otp-already-requested';
    }
    public function getTitle(): ?string
    {
        return 'Code already requested';
    }
    public function getStatus(): ?int
    {
        return 406;
    }
    public function getDetail(): ?string
    {
        return 'Please wait 1 minute before requesting another code';
    }
    public function getInstance(): ?string
    {
        return null;
    }
}

When throwing this error, i would expect the response to contain the title and details. Instead, the response looks as such. The title and detail fields are missing.

{
  "@context": "/contexts/OtpAlreadyRequestedError",
  "@id": "/otp_already_requested_errors",
  "@type": "OtpAlreadyRequestedError"
}

So for some context, I have the LoginRequest entity and I throw the error above in LoginRequestStateProcessor. This seems to happen when I have a group applied on the normalizationContext of LoginRequest for this operation. If I remove the serialization group, all properties get returned. Is it expected behavior that the serialization group should affect the entity's errors as well?

Mhh interesting groups are set there:

https://github.com/api-platform/core/blob/main/src/Symfony/EventListener/ErrorListener.php#L110

But they should not inherit from your original resource groups, would you be able to create a reproducer? You can also check inside the ErrorListener and the SerializeProcessor whether groups are correctly reset.

I have created a basic reproduction here. I'm not really sure whether I should reset the groups myself in the processor or if this should happen on its own. I am not overriding the ErrorListener, so that logic should still happen, right? Thanks!

To reproduce, one needs to run the following:

1. docker compose build && docker compose up -d
2. curl -k -X POST -H "Content-Type: application/ld+json" -d '{}' https://localhost/login_requests

Commenting out the groups from LoginRequest returns the whole error object.
