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 8 new columns ({'head_page_id', 'feature_delta', 'head_feature_count', 'head_observer', 'change_class', 'head_logged_at', 'prior_feature_count', 'prior_page_id'}) and 9 missing columns ({'page_id', 'observer_name', 'logged_at', 'photo_status', 'observer_code', 'disposition', 'legibility', 'feature_count', 'reason'}).

This happened while the csv dataset builder was generating data using
