[GitHub] [dubbo] beastqin opened a new issue, #12632: triple 协议 stub 调用无法捕获自定义异常甚至 RpcException
beastqin opened a new issue, #12632:
URL: https://github.com/apache/dubbo/issues/12632
version：dubbo 3.2.2
现象：使用 triple 协议 + IDL（protobuf stub），provider 端抛出`RpcException` 后，consumer 端无法捕获具体的 `code`，统一为Unknown，同理自定义异常也被处理为 Unknow RpcException。
Provider 端异常抛出代码：
```java
@Override
public ListFollowersResponse listFollowers(ListFollowersOptions request) {
throw new RpcException(BIZ_EXCEPTION, "test exception");
}
```
Consumer 端日志打印：debug get rpc ex: org.apache.dubbo.rpc.StatusRpcException: UNKNOWN : test exception
因为比较疑惑，Dubbo 3.2.0 版本开始 Triple 协议支持回传自定义异常，所以扒了下原因：
```java
if (hasStub) {
listener = new StubAbstractServerCall(invoker, TripleServerStream.this,
frameworkModel,
acceptEncoding, serviceName, originalMethodName, executor);
} else {
listener = new ReflectionAbstractServerCall(invoker, TripleServerStream.this,
frameworkModel, acceptEncoding, serviceName, originalMethodName, filters,
executor);
}
```
看上去 TripleServerStream 在存在 stub 被调用时，会选用默认关闭 Exception Wrapper 的序列化选项的 StubAbstractServerCall。
所以，使用 IDL 调用是无法处理自定义异常吗？以及标准的 RpcException 的处理似乎也有问题。后续会解决这个问题吗？
