I'm trying to pass data to an action inside the same controller. I'm using RedirectToAction, but I'm not succeeding. The action is called but the data I'm trying to pass to it has its values ​​null.

My Model:

public class PlaylistModel
{
    public Guid PlayListID { get; set; }
    [Display(Name = "Nome da Playlist")]
    public string NomePlayList { get; set; }
    [Display(Name = "Descrição")]
    public string Descricao { get; set; }
    [Display(Name = "Código")]
    public string CodigoPlayList { get; set; }
    public string Estado { get; set; }
    public string EmailUser { get; set; }
    public List<VideoThumbnails> VideosIdsYoutube { get; set; }
    [Display(Name = "Categorias")]
    public List<string> Categorias { get; set; }
}

This action receives the data, does the processing and calls the other action

[HttpPost]
public ActionResult CreatePlaylist(string Categorias, string NomePlayList)
{
    PlaylistModel playListModel = new PlaylistModel();
    playListModel.VideosIdsYoutube = AppCache.Instance.VideoParaAPI.VideoThumbnails.ToList();
    playListModel.Categorias = Categorias.Split(',').ToList();
    playListModel.NomePlayList = NomePlayList;
    playListModel.Estado = EnumEstadoDaPlayList.Nova.ToString();
    playListModel.EmailUser = AppUser.User.Email;

    var api = new AccessAPI.Playlist.AccessAPIPlaylist();
    var playlist = api.CriarNova(playListModel);

    if(playlist != null)
    {
        return RedirectToAction("ExibirPlaylist", new RouteValueDictionary(new { controller = "Playlist", action = "ExibirPlaylist", pPlayList = playlist }));
    }
    else
    {
        return Problem("Não foi possível criar a playlist!");
    }
}

This other action is called by the previous one, but the model arrives with null values

[HttpGet]
public ActionResult ExibirPlaylist(PlaylistModel pPlayList)
{
    var apiVideo = new AccessAPI.Video.AccessAPIVideo();
    var videos = apiVideo.ConsultarPorPlayListId(pPlayList.PlayListID).ToList();
    if(videos.Count > 0)
    {
        videos.ForEach(v => 
        {
            pPlayList.VideosIdsYoutube.Add(new Dommain.Cache.VideoThumbnails() { CanalID = v.CanalID, DataDePublicacao = v.DataDePublicacao, NomeDoCanal = v.NomeDoCanal, NomeDoVideo = v.NomeDoVideo, Thumbnail = v.Thumbnail, VideoId = v.VideoIdYoutube});
        });
    }
    return View();
}
