Hi, using the API /3/discover/movie I sometimes have films that have a poster_path, and when I use the API /3/movie/:id for the film: The poster_path in the response is null, why ?

Exemple :

• With https://api.themoviedb.org/3/discover/movie?api_key=<API_KEY>&language=fr-FR&include_video=false&include_adult=false&sort_by=popularity.asc&with_release_type=2%7C3&release_date.gte=2023-09-21&release_date.lte=2023-10-12

  [...]
