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 36 new columns ({'text', 'platform', 'fresh_source', 'original_utf8_bytes', 'source_path', 'commit', 'identity_keys', 'repository', 'detail_path', 'training_only', 'license', 'figure_limitation', 'known_version_paths', 'version_evidence', 'source_metadata', 'family_keys', 'raw_source_sha256', 'selected_version', 'prior_exposure', 'allowed_role', 'transformation_notice', 'split', 'identity_resolved', 'detail_sha256', 'family', 'representation', 'attribution', 'raw_source_bytes', 'sha256', 'raw_path', 'title', 'subjects', 'extraction_stats', 'domain', 'source_family_before_grouping', 'source_url'}) and 3 missing columns ({'token_offset', 'text_sha256', 'utf8_bytes'}).

This happened while the json dataset builder was generating data using
