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 ({'id', 'filename', 'metaData'}) and 2 missing columns ({'name', 'age'}).
This happened while the json dataset builder was generating data using
hf://datasets/aframson/lighthouse/file_database.json (at revision 8c8fbff0ca96e904d20a4657b9fae7c13606bacb)
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)
