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 5 new columns ({'img', 'a', 'r', 'url', 't'}) and 10 missing columns ({'authors', 'thumbnail', 'title', 'categories', 'downloadCount', 'txtLink', 'epubLink', 'readLink', 'languages', 'mobiLink'}).

This happened while the json dataset builder was generating data using
