    Problem Migrating Macros to Blocks

    I'm using Umbraco 13.2.2 and trying to migrate a macro to a block, and getting an "Object reference not set to an instance of an object" error.

    @inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Umbraco.Cms.Core.Models.Blocks.RichTextBlockItem>
        var folderId = Model.Content.Value("mediaFolderID");
        var media = Umbraco.Media(folderId);
        var selection = media.Children().OfType<Image>();

    The media.Children().OfType<Image>(); line is causing the object reference error, but I'm not sure why as I'm using the Media Picker to get mediaFolderID.

    I resolved the error by specifying the type, IPublishedContent, of the model value. And then I had to get the Id of the folder, rather than the whole object:

    var folderId = Model.Content.Value<IPublishedContent>("mediaFolderID");
    var media = Umbraco.Media(folderId.Id);
