使用异步方法加 RedisCache和MemoryCache Attribute会报错

                    if (context.ServiceMethod.IsReturnTask())
                    {
                        context.ReturnValue = Task.FromResult(JsonConvert.DeserializeObject(value,
                            context.ServiceMethod.ReturnType.GenericTypeArguments[0]));
                    }

context.ReturnValue是空值

"Message": "Exception has been thrown by the aspect of an invocation. ---> Object reference not set to an instance of an object.."
"InnerException":"Object reference not set to an instance of an object.",

returnValue Id = 405, Status = RanToCompletion, Method = "{null}", Result = "19"

异步读取redis key 返回null
