likefang opened a new issue #8281: URL: https://github.com/apache/dubbo/issues/8281
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. - [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 2.6.6 * Operating System version: linux * Java version: java8 ### Steps to reproduce this issue 1. 调用链为serviceA调用serviceB调用serviceC，整个调用链均为dubbo方式调用 2. serviceA调用serviceB为oneWay方式调用不关注返回结果，serviceB调用serviceC为正常的dubbo同步调用，但是serviceB获取到serviceC的返回结果为null，而不是包装过的response，造成解析结果是报NPE异常 3. 修改serviceA调用servoceB的调用方式为同步调用，问题解决，整个调用链路正常 4. 忽略第三部，换另外一种方式验证，在serviceB中添加fitter，清除掉oneWay方式调用的key，整个调用也正常进行 Pls. provide [GitHub address] to reproduce this issue. ### Expected Result What do you expected from the above steps？ ### Actual Result What actually happens?
