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 3 new columns ({'description', 'name', 'price'}) and 4 missing columns ({'products', 'users', 'cart', 'sales'}).
This happened while the json dataset builder was generating data using
hf://datasets/Testbase1/testsett/products.json (at revision a2f69efbd023a0734ffecb37792359df19e798c7)
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)
