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 4 new columns ({'metadata', 'event_id', 'timestamp', 'event_type'}) and 9 missing columns ({'location', 'education', 'device', 'account_age_days', 'age', 'loyalty_status', 'premium', 'gender', 'income'}).

This happened while the csv dataset builder was generating data using

hf://datasets/SuriyaSureshkumar/ecommerce_features/event_logs_sample.csv (at revision 9290cc7935d18516a5bbdecbb27ff791ee667346)

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)
