yes, so I don't understand why I am getting this. something wrong with how i am creating this versioned dataset

class HistogramDataSet(AbstractVersionedDataSet):

    def __init__(self, filepath: str, version: Version = None, credentials: Dict[str, Any] = None):
        _credentials = deepcopy(credentials) or {}
        protocol, path = get_protocol_and_path(filepath)
        self._protocol = protocol
        self._fs = fsspec.filesystem(self._protocol, **_credentials)
        super().__init__(
            filepath=PurePosixPath(path),
            version=version,
            exists_function=self._fs.exists,
            glob_function=self._fs.glob, )

    def _load(self):
        load_path = get_filepath_str(self._filepath, self._protocol)
        log.info(f'load_path: {load_path}')
        try:
            with self._fs.open(load_path) as f:
                return json.load(f)
        except FileNotFoundError:
            return None

    def _save(self, data) -> None:
        """Saves data to the specified filepath."""
        save_path = get_filepath_str(self._filepath, self._protocol)
        with self._fs.open(save_path, mode="w") as f:
            json.dump(data, f, default=dumper)
        self._invalidate_cache()

for versioning I am using kedro functionality
