MusicClient.Get returns an error when LookupOptions is not null

[Nooodles]

Hi,

I don't know exactly where it comes from, but it seems that I can make MusicClient.Get() work fine without any option, but I got a "Bad Request" error when I add LookupOptions.

Sample code:

var results = client.Find("Daft Punk").Result;
var artistId = results.Artists.Items.First().Id;
var artistDetails = client.Get(artistId).Result; //works fine
artistDetails = client.Get(artistId, new LookupOptions(true)).Result; //Error: bad request

Any idea where this could come from?
Thanks!
