Client GetFriendsListRequest will not allow me to show or return statistics

The following code returns Object reference not set to an instance of an object at the line with the comment.

PlayFab.ClientModels.GetFriendsListRequest request = new PlayFab.ClientModels.GetFriendsListRequest();

request.IncludeFacebookFriends = true;
request.IncludeSteamFriends = false;
request.ProfileConstraints.ShowStatistics = true; //null reference occurs here

PlayFabClientAPI.GetFriendsList(request, result => {
   DisplayFriends(result.Friends);
}, error => Debug.LogError(error.GenerateErrorReport()));

If I exclude the line "request.ProfileConstraints.ShowStatistics = true;" the code runs without the error, however, no statistics are returned within Profile.

I have enabled Statistics in ALLOW CLIENT ACCESS TO PROFILE PROPERTIES:

You'll want to initialize a Profile Constraints object, changing line 5 like so:

request.ProfileConstraints = new PlayerProfileViewConstraints() {ShowStatistics = true};

(The {}s after the constructor allow you to set field values on the new object inline, you could alternatively put it in a variable and initialize it separately.)

Thanks Brian, that solved the initial problem but created another. I now get a null reference for FacebookInfo.facebookId. It was working before your solution above.

details.FacebookID = f.FacebookInfo.FacebookId; // object reference is null

private void GetFriends()
    {
        PlayFab.ClientModels.GetFriendsListRequest request = new PlayFab.ClientModels.GetFriendsListRequest();
        request.IncludeFacebookFriends = true;
        request.IncludeSteamFriends = false;
        request.ProfileConstraints = new PlayerProfileViewConstraints() { ShowStatistics = true };
        PlayFabClientAPI.GetFriendsList(request, result => {
            DisplayFriends(result.Friends);
        }, error => Debug.LogError(error.GenerateErrorReport()));
    }


    private void DisplayFriends(List<PlayFab.ClientModels.FriendInfo> friends)
    {
        friends.ForEach(f => {
        Debug.Log(f.FriendPlayFabId);
        GameObject friend = Instantiate(FriendItemPrefab, FriendsListParent.transform) as GameObject;
        //Image ProfilePic = null;


        if (FriendsListParent != null)
        {
            //friend.transform.SetParent(FriendsListParent.transform, false);
            if (friend != null)
            {
                //Store friend values                    
                FriendDetails details = friend.GetComponent<FriendDetails>();
                details.PlayFabID = f.FriendPlayFabId;
                details.FacebookID = f.FacebookInfo.FacebookId; //NULL REFERENCE HERE
                details.DisplayName = f.TitleDisplayName;
                //grab the level and xp stats 
                Debug.Log("Statisitcs length = "+ f.Profile.Statistics.Count);
                
                foreach (var stat in f.Profile.Statistics)
                {
                        if (stat.Name == "level")
                            details.Level = stat.Value.ToString();


                        if (stat.Name == "xp")
                            details.XP = stat.Value.ToString();
                }
                


                //for now, query Facebook to retreive image
                FetchFirendsProfileImage(details.FacebookID, friend);


                //display the level and xp stats if not null
                if (!string.IsNullOrEmpty(details.Level))
                    friend.transform.Find("RankBase/Rank").gameObject.GetComponent<Text>().text = details.Level;
                
                //Add onClick Listener to the invite button
                friend.transform.Find("Invite").gameObject.GetComponent<Button>().onClick.AddListener(() => friendlyMatchCtlr.ChallengeFriend(friend.transform.Find("Invite").gameObject.GetComponent<Button>(), details));
                DisableButton(friend.transform.Find("Invite").gameObject.GetComponent<Button>());


                //Add onClick Listener to the chat button
                friend.transform.Find("Chat").gameObject.GetComponent<Button>().onClick.AddListener(() => chatManager.ShowPMPopup(friend.transform.Find("Chat").gameObject.GetComponent<Button>(), details));
            }
            else Debug.Log("The friend gameobject is null");
        }


        });// end foreach


    }

As a temporary work around I implemented a friendleaderboardaroundplayer however it does not provide access to the friends facebook ids in the results.

I only need to know it once a button is clicked for a specific friend. Is there an API call to load a friend's profile info with the Facebook ID?

I have tried using a second call to GetFriendsList WITHOUT profile view constraints when a button for a specific friend is clicked...the GetFriendsList is returning null values for FacebookInfo.FacebookId....

//retrieve facebookId from GetFriendsList
                PlayFab.ClientModels.GetFriendsListRequest request = new PlayFab.ClientModels.GetFriendsListRequest();
                request.IncludeSteamFriends = false;
                PlayFabClientAPI.GetFriendsList(request, result => {
                    result.Friends.ForEach(f=> {
                        if (f.FriendPlayFabId == details.PlayFabID)
                        {
                            details.FacebookID = f.FacebookInfo.FacebookId; //NULL HERE
                            Debug.Log("Successfully retrieved facebook ID: " + f.FacebookInfo.FacebookId); //NULL HERE
                        }
                        else
                            Debug.Log(f.FriendPlayFabId+" != "+details.PlayFabID);
                    });//end foreach
                    
                }, error => Debug.LogError(error.GenerateErrorReport()));

What are the Title ID and the PlayFab IDs that you're using for the test, so that we can have a look?

I think you're correct Brendan. The test user is not an actual FB friend of my developer account on Facebook.I tested again with 2 test users that are Facebook friends and it appears to work. Thanks!

Is there any ETA for resolving the profile contraints bug? returning the FacebookInfo with constraints will eliminate many additional API calls within our app.

We'll be posting on the other thread, where we're tracking on that issue, as soon as we have an update.
