The dataset generation failed because of a cast error
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 12 new columns ({'crafting_cost_base', 'required_materials_qty', 'item_id', 'craftable', 'base_value', 'rarity', 'source_method', 'usage_effect', 'tier', 'required_materials_ids', 'item_type', 'item_name'}) and 7 missing columns ({'event_type', 'event_id', 'affected_items', 'event_name', 'description', 'start_date', 'end_date'}).
This happened while the csv dataset builder was generating data using
hf://datasets/mvfflin/dummy-ingame-items/item_metadata.csv (at revision 22d2784d1a6553735ca1be3afa8d20f9569e0cb7)
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)
