   也没有任何报错，官网里说“往 3.0 版本的升级过程将会是完全透明的，用户无需做任何业务改造，升级 3.0.x 后的框架行为将保持与 2.x 版本完全一致。”，但是明显感觉“序列化方面”有不兼容

   今天定位出问题了，原因像是dubbo3.0.x，支持间接传递“dubbo调用上下文attaments参数”，导致后续逻辑误判，执行了额外的序列化策略

   22年上半年就发现了，那些什么“安全扫描，动不动扫描出dubbo有安全漏洞”，安全部门催促升级，升级了consumer侧的“返序列化结果”又为空

   可以提供一个可以复现的 demo 吗，另外看一下 Dubbo 是否有对应的报错日志

   没有任何dubbo相关的报错，就是结果为空对象。
   
   场景描述：
   golang语言网关F应用通过“dubbo-go”组件，泛化invoke调用europa应用的dubbo rpc服务，然后europa应用又调用我这边aladdin应用的dubbo服务查询“关键信息数据”，接收到的结果为“一个空对象”，没有任何报错

   还有一个情况是：如果直接走“我这边europa”，通过@GatMapping暴露一个http接口调用，就能正常返回数据，查询条件查询环境一模一样；
