Photos can't create album

[mirkoevo]

Hi,

I have a new problem with Photos unders OS X/objc.
Now it seems I can't create albums anymore, and I don't know if I can workaround the problem in some ways.
This is the output:

2017-02-27 10:23:55.949 App[22136:11534254] serviceBase:<GDataServiceGooglePhotos: 0x6200001c1a40> objectFetcher:GTMHTTPFetcher 0x1036a8c80 (https://photos.googleapis.com/data/feed/api/user/114209999584000922529) failedWithStatus:501 data:Insert is no longer supported

Do you have any ideas why it returns "Insert is no longer supported" ?
(tested with old/new auth token)

Thank you.

    GDataEntryPhotoAlbum *newAlbum = [GDataEntryPhotoAlbum albumEntry];
    
    [newAlbum setTitleWithString:albumName];
    [newAlbum setPhotoDescriptionWithString: [_album objectForKey: @"description"]];
    [newAlbum setLocation: [_album objectForKey: @"location"]];
    [newAlbum setAccess:access];
    
    NSURL *postLink = [[[_picasaController albumFeed] postLink] URL];
    
    [[_service mainThreadProxy] fetchEntryByInsertingEntry:newAlbum
                                                    forFeedURL:postLink
                                                      delegate:self

You'd likely need to use the support areas for the Picasa Web Albums API. But taking a quick peek there, it looks like there are several posts from folks using a variety of languages, that mutations started failing for some reason.
