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 ({'year'}) and 3 missing columns ({'last_year', 'state', 'first_year'}).

This happened while the csv dataset builder was generating data using

Laser Strikes on Aircraft Reported to the FAA, 2021-2025 (by year, state, city)

Aggregated from FAA laser-strike reports (54,722 reports, 2021-2025), compiled by FlightFinder. Files: reports by year (with crew injuries), by state, and top cities per state. Fun fact hiding in the data: the top "city" in America is Mather, CA - a Sacramento suburb - an artifact of how the FAA fills the city field (see https://himaxym.com/stories/laser-strike-capital).
