Happening to me also. Not sure i this helps:

private static async Task<IFCMResponse> SendFCMMessage(string deviceId, Dictionary<string, string> data)
        {
            FCMClient client = new FCMClient("...snip");

            var message = new Message()
            {
                To = deviceId,
                Priority = MessagePriority.high,
                TimeToLive = 30,
                Data = data
            };
           
            return await client.SendMessageAsync(message);

        }

Actually, my current NPE is in: Exception thrown: 'System.NullReferenceException' in System.Web.dll but i've seen it say mscorelib also.
