DatasetGenerationCastError: An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 3 new columns (metadata_A, id, metadata_B) and 3 missing columns (c_root_id_A, upvote_ratio, c_root_id_B).

This happened while the json dataset builder was generating data using

hf://datasets/stanfordnlp/SHP-2/stackexchange/stack_academia/train.json (at revision aeb14be2c479ff704697d7e3d794fbf2537fdbed)

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)
