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 3 new columns ({'decision', 'detection_id', 'reason'}) and 10 missing columns ({'station_name', 'member_count', 'flyway', 'total_calls', 'representative_confidence_milli', 'representative_detection_id', 'started_at', 'species_code', 'ended_at', 'classification'}).
This happened while the csv dataset builder was generating data using
