Api get Movie detail return nil for production_companies and production_countries

[ngqth]

The code I tried is taken from the wiki:

MovieMDB.movie(apikey, movieID: 7984, language: "en"){
      apiReturn, movie in
      if let movie = movie{
        print(movie.title)
        print(movie.revenue)
        print(movie.genres[0].name)
        print(movie.production_companies?[0].name)
      }
    }

production_companies, production_countries appear in apiReturn, but

print(movie.production_companies?[0].name)

return nil
