Hugging Face ML 4 Games Course 1

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 3 new columns ({'Demo', 'Status', 'Candidature Code'}) and 4 missing columns ({'ApplicationId', 'ApplicationStatus', 'DemoApplication', 'ApplicationObservations'}).

This happened while the json dataset builder was generating data using

hf://datasets/huggingface-ml-4-games-course/ml-4-games-course-certification/candidates.json (at revision 1a4beca16445bf2717b532a697db06bdd2ef705d)

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)
