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 ({'modality_concept_id', 'accession_id', 'visit_occurrence_id', 'image_study_uid', 'procedure_occurrence_id', 'local_path', 'image_series_uid', 'image_occurrence_date'}) and 5 missing columns ({'image_feature_concept_id', 'image_feature_event_id', 'image_feature_id', 'image_feature_type_concept_id', 'image_feature_event_field_concept_id'}).

This happened while the csv dataset builder was generating data using
