拦截器主动抛出异常为何还会执行后续的response.getResult()操作？

此处handleError的时候会出来响应码不为200的，并包装成网络错误
某个拦截器的onError方法主动抛出了自定义异常，会被最初的handleSyncWithException的catch (Throwable th)拦截。
此时为何又要去response.getResult()？
如果getResult一般会抛出数据转换异常，这样导致自定义拦截器中抛出的自定义异常丢失。
这个如何解决？

Start by tracing the exception flow through handleError, handleSyncWithException, the interceptor onError method, and response.getResult(). Reproduce a non-200 response where onError throws a custom exception, then verify that the custom exception is preserved and data conversion is not invoked afterward.
