OnAudioQuery.queryArtwork(album.id, ArtworkType.ALBUM) do not produce an artwork (iOS 17.2.1)

[usarthurchoi]

Uint8List? artwork =
await _audioQuery.queryArtwork(album.id, ArtworkType.ALBUM);
if (artwork != null) {
artworks[album.id] = artwork;
}

Result was that artwork was null. The album has an artwork definitely. From the following unit test written in Swift, I was able to get the artwork without issues.
==>
func getAlbumArtwork(album: MPMediaItemCollection) -> UIImage? {
guard let representativeItem = album.representativeItem,
let artwork = representativeItem.value(forProperty: MPMediaItemPropertyArtwork) as? MPMediaItemArtwork else {
return nil
}

    // You can specify the size of the artwork image you need
    let imageSize = CGSize(width: 100, height: 100) // Example size
    return artwork.image(at: imageSize)
}

<==

Maybe the problem may originate from not using MPMediaItemCollection.representativeItem for an album.
