raise NotImplementedError(f"Loading a dataset cached in a {type(self._fs).__name__} is not supported.")
NotImplementedError: Loading a dataset cached in a LocalFileSystem is not supported.

Start with datasets_test.py and the load_dataset(path="json", data_files="global_test.json", cache_dir="cache/huggingface/datasets") call shown in the report. Reproduce the failure and inspect the dataset-loading path around the LocalFileSystem NotImplementedError. Done means the JSON dataset loads successfully from the configured cache without this exception.
