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 7 new columns ({'copies', 'valid_loans', 'title', 'closed_loans', 'overdue_loans', 'available_copies', 'active_loans'}) and 4 missing columns ({'decision', 'reason', 'circulation_status', 'loan_id'}).

This happened while the csv dataset builder was generating data using

hf://datasets/SOTAagi2030/Library-Circulation-Audit-270/reports/title-status.csv (at revision 945b549c103151718c204b2f30690e658f50058c), ['hf://datasets/SOTAagi2030/Library-Circulation-Audit-270@945b549c103151718c204b2f30690e658f50058c/data/loan-audit.csv', 'hf://datasets/SOTAagi2030/Library-Circulation-Audit-270@945b549c103151718c204b2f30690e658f50058c/reports/title-status.csv']

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)
