InvalidLikeRequest - Microsoft.Office.Server.Social.SPSocialException: The operation is invalid for the target's current state

Hi,

I am having a play with the social features in SharePoint 2013 using the server object model. I can retrieve a team site news feed with no problem, with associated likes, replies etc. However, when I go to write to the feed (e.g. by trying to "like" a post which I currently do not like), I am getting nothing but errors. Specifically...

Microsoft.Office.Server.Social.SPSocialException: The operation is invalid for the target's current state. Internal type name: Microsoft.Office.Server.Microfeed.MicrofeedException. Internal error code: 32.   at Microsoft.Office.Server.Social.SPSocialUtil.TryTranslateExceptionAndThrow(Exception exception)   at Microsoft.Office.Server.Social.SPSocialUtil.InvokeWithExceptionTranslation[T](ISocialOperationManager target, String name, Func`1 func)   at Microsoft.Office.Server.Social.SPSocialFeedManager.<>c__DisplayClass45`1.<s2sinvoke>b__44()   at Microsoft.Office.Server.Social.SPSocialUtil.InvokeWithExceptionTranslation[T](ISocialOperationManager target, String name, Func`1 func)   at Microsoft.Office.Server.Social.SPSocialFeedManager.LikePost(String postId)   at wall.getPosts()

Error code 32 is "InvalidLikeRequest". If I try to "unlike" the request, it returns error code 38 (InvalidUnlikeRequest_alreadyMarkedAsUnlike) which I obviously expect to happen, as you can't unlike something you don't already like. But what it tells me is that the thread / post ID I am passing to the feedManager.likepost(string ID) method is correct as the error changes depending on whether I already like it or not.

Abbreviated code below which should "like" the most recent post in a site news feed:

  using (SPSite site = new SPSite(url))
                {
                    SPServiceContext serviceContext = SPServiceContext.GetContext(site);
                   
                    using (new SPServiceContextScope(serviceContext))
                    {
                        SPUser thisUser = site.RootWeb.CurrentUser;
                        SPUserToken token = thisUser.UserToken;

                        UserProfileManager manager = new UserProfileManager(serviceContext);

                        UserProfile profile = manager.GetUserProfile(thisUser.LoginName);

                        SPSocialFeedManager feedManager = new SPSocialFeedManager(profile, serviceContext);

                        SPSocialFeed feed = feedManager.GetFeedFor(teamSiteAddress, new SPSocialFeedOptions());

                        SPSocialThread thread = feed.Threads[0];
                        feedManager.LikePost(thread.Id);
                    }
  }

Any help greatly appreciated
