在利用edge做边缘服务与其他服务交互时，证书的校验出现异常。然而我发现在发生异常的时候，异常被handler捕获了，这个异常并没有被抛出，而抛出了490，请问在现有的代码中，是否存在钩子之类的方法可以拿到该异常？
RestClientInvocation.java#invoke(Invocation invocation, AsyncResponse
asyncResp)
```
clientRequest.exceptionHandler(e -> {
invocation.getTraceIdLogger().error(LOGGER, "Failed to send request,
local:{}, remote:{}.",
getLocalAddress(), ipPort.getSocketAddress(), e);
throwableHandler.handle(e);
});
```
