Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 2 new columns ({'tasks', 'length'}) and 8 missing columns ({'task_index', 'frame_index', 'timestamp', 'next.done', 'next.success', 'index', 'observation.clock.clock', 'next.reward'}).

This happened while the json dataset builder was generating data using

hf://datasets/Sraghvi/subset-0-rosbags-lerobot/meta/episodes.json (at revision 8b49f6ccb20c53e3212076acf38f20c2b9533bda)

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)
