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 ({'language', 'title', 'date', 'url'}) and 2 missing columns ({'query', 'screenshot'}).

This happened while the json dataset builder was generating data using

hf://datasets/Lord-Jim/my-json/1_source_file_1m.json (at revision 9e92e7efc6ef0643a4643ad10e45cc7f26e08313)

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)
