`JSON` attributes do not show up as valid json in event attributes

Comienza con el método emit del handler y la construcción de HTTPLogItem mostrada en el informe; después, sigue cómo se serializa log_ctx a través de LogsApi.submit_log. Reproduce el ejemplo de logger.debug con x_request_body y verifica que los atributos del evento enviado conserven valores de objeto JSON válidos en lugar de mostrarse como cadenas.

Describe the bug
A clear and concise description of what the bug is.
When a valid json is passed as value of a custom event atrribute, In logs it is show as a string and not a json object

To Reproduce

# in the handler

    def emit(self, record):
        env = os.getenv("APP_ENV", "local")
        log_ctx: LogCtxDict = record.__dict__.get("log_ctx", {})
        tags_dict = log_ctx.pop('tags', {})
        tags = [f"{k}:{v}" for k, v in tags_dict.items()]
        tags.append("env:{}".format(env))
        tags_merged = ",".join(tags)
        body = HTTPLog(
            [
                HTTPLogItem(
                    ddsource="python",
                    ddtags=tags_merged,
                    hostname="vv-anyscale-ray-aps1",
                    message=self.format(record),
                    service="vv-ap-thumbnails-v1-{}-service".format(env),
                    timestamp=str(datetime.fromtimestamp(record.created).astimezone().timestamp()),
                    level=record.levelname.lower(),
                    **record.__dict__.get("log_ctx", {})
                )
            ]
        )
        try:
            with ApiClient(self.dd_configuration) as api_client:
                resp = LogsApi(api_client).submit_log(content_encoding=ContentEncoding.GZIP, body=body)
                if "errors" in resp:
                    self.handleError(record)

        except (Exception, ):
            self.handleError(record)




logger.debug(
    "Test debug log",
    log_ctx={
        "x_request_body": json.dumps({"clip_id": "66abc57369bbe0000782ef42"}),
    }
)
