Hello. I have the following question. I call the nextBatch() method on MusicItemCollection<Album> to get the next collection of artist albums. Here is my method:

func allAlbums2(artist: Artist) async throws -> [Album] {

var allAlbums: [Album] = [] artist.albums?.forEach { allAlbums.append($0) }

     guard let albums = artist.albums else { return [] }
     var albumsCollection = albums
    
     while albumsCollection.hasNextBatch {
        
         let response = try await albumsCollection.nextBatch()
        
         if let response {
             albumsCollection = response
             var albums = [Album]()
             albumsCollection.forEach({ albums.append($0)})
             allAlbums.append(contentsOf: albums)
         }
     }
    
     return allAlbums
 }

The problem is as follows. Sometimes it happens that some albums not in nextBatch are not returned (I noticed one, I didn't check the others). This happens once every 50-100 requests. The number of batches is returned the same when the album is skipped. The same albums are returned in the batch where the album was missed. I have a question, do I have a problem with multi-threading or something else or is it a problem in the API. The file contains prints of the returned batches. One with a missing album, the other without a missing one. There are about 3000 lines in the file. I will be grateful for a hint or an answer. Thank you!
