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 6 new columns ({'scheduled_attendees', 'public_room', 'occupied_slots', 'last_end_slot', 'first_start_slot', 'scheduled_bookings'}) and 2 missing columns ({'request_id', 'decision'}).
This happened while the csv dataset builder was generating data using
