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 ({'id', 'power_class', 'name', 'power_kw'})

This happened while the csv dataset builder was generating data using

hf://datasets/TarekMasryo/Global-EV-Charging-Stations/data/charging_stations_2025_world.csv (at revision 6efd66205fe2c3477e03674658830bf23a24bb1c)

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)
