The dataset generation failed because of a cast error

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 ({'messages'}) and 7 missing columns ({'discussion', 'image_url', 'views', 'fancy_title', 'tags', 'title', 'created_at'}).

This happened while the json dataset builder was generating data using

hf://datasets/wangzhang/mongoDB_community_hot/mongoDB_data_hot.jsonl (at revision af70a7e8c88f0324d190036b17b260a420dceeec)

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)
