getting java.lang.String cannot be cast to java.lang.Void error

I am getting this error when trying to parse my json

java.lang.String cannot be cast to java.lang.Void

The stacktrace says that the error is coming from the "Movie " class

The classes that I am using are as follows

@Model
@Serializable
data class MovieList(val watchers: Int, val movie: Movie)

@Serializable
data class Movie(val title: String, val year: Int, val ids: MovieIds)

@Serializable
data class MovieIds(val trakt: Int, val slug: String, val imdb: String, val tmdb: Int)

and the json data looks like this

[
  {
    "watchers": 21,
    "movie": {
      "title": "TRON: Legacy",
      "year": 2010,
      "ids": {
        "trakt": 1,
        "slug": "tron-legacy-2010",
        "imdb": "tt1104001",
        "tmdb": 20526
      }
    }
  },
  {
    "watchers": 17,
    "movie": {
      "title": "The Dark Knight",
      "year": 2008,
      "ids": {
        "trakt": 4,
        "slug": "the-dark-knight-2008",
        "imdb": "tt0468569",
        "tmdb": 155
      }
    }
  }
]

For me its not a big problem, i just used gson instead of kotlinx serialization and when the bug its fixed i will exchange it ^_^
