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 2 new columns ({'Name', 'CategoryID'}) and 2 missing columns ({'errors', 'data'}).

This happened while the json dataset builder was generating data using

hf://datasets/antoinelb7/alloprof/data/questions/categories.json (at revision 0faa90fee1ad1a6e3e461d7be49abf71488e6687)

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)
