[GitHub] [dubbo] victorqian opened a new issue, #12256: 3.2.0版本调用多协议接口，出现空指针错误
victorqian opened a new issue, #12256:
URL: https://github.com/apache/dubbo/issues/12256
依赖：
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo</artifactId>
<version>3.2.0</version>
</dependency>
Provider端使用3.0.10版本，并且服务暴露双协议: dubbo和tri协议
Consumer升级至3.2.0版本，进行调用时，报如下错误：
[2023-05-08 15:15:08,503] [WARN ] [org.apache.dubbo.rpc.protocol.tri.stream.StreamUtils ?] [main] dstTraceId:[] [DUBBO] Meet exception when convert single attachment key:version value=null, dubbo version: 3.2.0, current host: 192.168.3.217, error code: 4-1. This may be caused by , go to https://dubbo.apache.org/faq/4/1 to find instructions. []
java.lang.NullPointerException: null
at org.apache.dubbo.rpc.protocol.tri.stream.StreamUtils.convertSingleAttachment(StreamUtils.java:137)
at org.apache.dubbo.rpc.protocol.tri.stream.StreamUtils.convertAttachment(StreamUtils.java:107)

at org.apache.dubbo.rpc.protocol.tri.TripleInvoker.invokeUnary(TripleInvoker.java:247)
经过debug发现，ServiceDiscoveryRegistryDirectory中的invoke方法，在协议变更时，会往Attachment中设置group和version参数，如果这两个参数未使用，则会配设置为null，最后导致空指针
