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 1 new columns ({'customer_id'}) and 1 missing columns ({'product_id'}).

This happened while the csv dataset builder was generating data using
