Cybersource payments not working

[Unarelith]

Python version: 3.11.2

When using version 1.0.0 from pip, I have the following error:

Object of type RuleResultItem is not JSON serializable

I added the following function which I found here: https://stackoverflow.com/a/34844428

import datetime

def object_to_dict(obj):
    if isinstance(obj, (str, bool, int, float, datetime.datetime, datetime.date, datetime.time, dict)):
        return obj
    data_dict = {}
    try:
        all_keys = obj.__dict__.keys()  # vars(obj).keys()
    except AttributeError:
        return obj
    fields = [k for k in all_keys if not k.startswith('_')]
    for field in fields:
        val = getattr(obj, field)
        if isinstance(val, (list, tuple)):
            data_dict[field] = []
            for item in val:
                data_dict[field].append(object_to_dict(item))
        else:
            data_dict[field] = object_to_dict(val)
    return data_dict

And used it in models.py:

class PaymentAttributeProxy:
    # ...

    def __setattr__(self, key, value):
        if key == "_payment":
            return super().__setattr__(key, value)
        try:
            data = json.loads(self._payment.extra_data)
        except ValueError:
            data = {}
        data[key] = value

        self._payment.extra_data = json.dumps(data, default=object_to_dict) # <= here

After that it seems to work perfectly, but it isn't an ideal solution.

Would anyone know why this error appears and a better way to fix it?

Also, the pip package should probably receive an update if there is a possibility of fixing this, since there is another Cybersource-related fix that's not released yet.

Was this working for you with a previous version of django-payments?
