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 ({'Question'}) and 2 missing columns ({'QuestionText', 'Note'}).

This happened while the csv dataset builder was generating data using

hf://datasets/Anahia/stackoverflow_survey_schemas/schema_2017.csv (at revision c50a353d4fe1dd98bf34a0d7c090d30b90be4a27), ['hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2016.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2017.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2018.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2019.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2020.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2021.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2022.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2023.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2024.csv', 'hf://datasets/Anahia/stackoverflow_survey_schemas@c50a353d4fe1dd98bf34a0d7c090d30b90be4a27/schema_2025.csv']
