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 9 new columns ({'ratio_ci95_high', 'age_adjusted_mot_initial_failure_ratio', 'prs_pct', 'initial_fail_pct', 'strict_failures_n', 'prs_n', 'strict_fail_pct', 'ratio_ci95_low', 'initial_failures_n'}) and 6 missing columns ({'over_representation_ratio', 'national_failure_items_per_100_tests', 'failure_items_per_100_tests', 'excess_pp', 'initial_tests_2024', 'defect_group'}).

This happened while the csv dataset builder was generating data using
