LuaPanda调试UnLua时，查看TArry时会断开连接。

[lzxcs]

环境：UE4 + VSCode + LuaPanda
问题：调试UnLua时，查看C++的TArry时会断开连接，并且无法查看TArry的值。

1.我用了原版Unlua进行测试https://github.com/Tencent/UnLua
2.增加了LuaSocket库，然后在TPSCharacter.cpp里新增了一个：
UPROPERTY(BlueprintReadOnly)
TArray TestArray;
3.在BP_PlayerCharacter_C.lua中增加对TestArray存取操作，然后断点打在存取操作上。
4.开始调试，运行UE4 PIE，然后断住，尝试悬停查看TestArray数值。
5.据异常抛出应该是：
LogUnLua: Error: [Plugins/UnLua/Source/UnLua/Private/LuaCore.cpp:2647] Lua error message: [string "Common/LuaPanda.lua"]:2344: '__index' chain too long; possible loop

收到，我们最近会看一下

[lzxcs]

更正一下，实际异常抛出是在LuaCore.cpp 的 int32 ReportLuaCallError(lua_State *L) 方法的if (Type == LUA_TSTRING)这个判断内

有个临时解决方案：详见#64 (comment)

非常感谢，我会测试一下然后整理成文档方便大家看到
