public static void SaveWxCloud<T>(T playerData)

        {

            if (playerData == null) return;

            WX.cloud.CallFunction(new CallFunctionParam()

            {

                name = "upLoadData",

                data = JsonUtility.ToJson(playerData),

                //data = playerData,

                success = (res)=>

                {

                    Debug.Log($"保存{playerData}成功,{res.result}");

                },

                fail = (res)=>

                {

                    Debug.Log($"保存{playerData}失败，错误原因：{res.errMsg}");

                }

            });

        }

我按教程填的 data = JsonUtility.ToJson(playerData),

出现错误提示 保存HappyBirdStudio.MiniParty.PlayerData失败，错误原因：parameter should be object instead of string;

但如果改成data = playerData,转成小游戏代码后又提示数据为空，但其实数据并不为空。这个异常在调用服务器的uploadData前就抛出了

TypeError: Cannot convert undefined or null to object
