Hi all,  
I’m currently setting up my game with Nakama and its such a nice experience so far, but i stumbled upon a bug in the Unity SDK i guess.

I call the function `DeleteFriendsAsync` like in the example project “JollyRogers” and i get the following error:

> `NullReferenceException: Object reference not set to an instance of an object Nakama.UnityWebRequestAdapter+<SendRequest>d__11.MoveNext () (at Assets/External/Nakama/UnityWebRequestAdapter.cs:130) UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)`

I also copied the example code from the docs(with my data), which throws the same error and its also not working in the example project “JollyRogers” for me.

My Setup:  
Unity: 2018.4.16f1  
Nakama Server: 2.4.1  
Nakama SDK: 2.3.1

Should i create a git issue about it?

@DamarXCV I can’t reproduce this so far. Did you download the Unity client from the Asset Store releases or from GitHub?

I downloaded it from the asset store.  
Did you tried to reproduce it with the sample project?  
This is what i just tried again:

1. Download the project from the [repo](https://github.com/heroiclabs/unity-sampleproject)
2. Start the server under unity-sampleproject-master\ServerModules `docker-compose -f docker-compose-postgres.yml up`
3. Open the `MainScene.unity`
4. Build the project for desktop
5. Add a Sufix to the `NakamaSessionManagerSingleton`
6. Start the game in unity (user 1)
7. Start the builded app (user 2)
8. Add user 1 with user 2
9. user 1 rejects the request and throws the error

I’m on windows but its also happening on android

I just replaced the Nakama SDK (v2.3.2) from the sample project with the **[nakama-unity](https://github.com/heroiclabs/nakama-unity)** repo (v2.4.0-dev) and its working.
