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 18 new columns ({'request_mode', 'volume', 'oi', 'ltq', 'atp', 'vtt', 'feed_timestamp', 'close', 'cp', 'tbq', 'tsq', 'ltt', 'ltp', 'low', 'open', 'received_timestamp', 'high', 'iv'}) and 7 missing columns ({'depth_level', 'ask_qty', 'ask_price', 'timestamp', 'tick_id', 'bid_qty', 'bid_price'}).

This happened while the csv dataset builder was generating data using
