1.2.0 albums.changeSettings return value issue

In the 1.2.0 docs for changeSetting, the return is doc'ed as the AlbumID (I guess it could be null since you pass the ID as an arg in the first place?)
But when I actually ran the command to update the desc of a testing album I was working on, I got back this reply:
Is there no return type from this method (I'll update doc) or will 'result' sometimes contain some sort of info about the operation and should be looked at?
