Collection Manager RemoveFromCollection

[bakes82 167]

Whats the way to get a  box set to pass in to the RemoveFromCollection method?  The rest api just takes in the internal id which is what Im passing to the GetItemById method

var existingCollection = _libraryManager.GetItemById(collection.CollectionId);
        _collectionManager.RemoveFromCollection(existingCollection as BoxSet, mediaItems.Select(x => x.InternalId)
                                                                             .ToArray());

No collection exists with the supplied Id
   at Emby.Server.Implementations.Collections.CollectionManager.RemoveFromCollection(BoxSet collection, Int64[] itemIds)

What is the collection object?

The "collection" object is my custom class, the collectionId is the long - internal id that you need to use to pass in to _collectionManger.AddCollection, and to delete a collection you use the BaseItem from GetItemById its weird this remove from collection takes in a boxsex, so I need the magic to get a boxset item from a internal long id

The message of the exception that gets thrown is outdated, and that will be fixed, but what is happening is you passed in null.

Logging will probably be needed to capture what is being passed into GetItemById, making sure it's non-zero, as well as what comes out of that.
