BenchFlow 3

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 3 new columns ({'instType', 'instId', 'markPx'}) and 2 missing columns ({'asks', 'bids'}).

This happened while the json dataset builder was generating data using

hf://datasets/benchflow/artifacts/data/mark_price_swap.json (at revision f88890c937f8d8371abf08858de22cd4fdbdf978)

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)
