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 ({'date', 'url', 'type', 'summary', 'tags', 'title', 'content'}) and 4 missing columns ({'articles', 'source', 'count', 'scraped_at'}).

This happened while the json dataset builder was generating data using

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)
