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 ({'type'}) and 3 missing columns ({'downloaded_timestamp', 'url', 'created_timestamp'}).

This happened while the json dataset builder was generating data using

zip://test.jsonl::hf://datasets/lexlms/lex_files@6b471f8873a7005a58cbd9f877971e4bfe47c173/canadian_legislation.zip

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)
