The Dubbo remote call has a Seata error: "because 'branchType' is null.

[AllKai]

Version:

dubbo：3.2.15 jdk：21 springboot：3.3.3 seata：2.1.0(apache seata) spring.cloud.version：2023.0.3 spring.cloud.alibaba.version：2023.0.1.2

If you set up according to the versions mentioned above, this issue will occur when the caller makes a remote call to an interface that does not have any transaction annotations; the error appears on the caller's side：

org.apache.dubbo.rpc.RpcException: Failed to invoke the method getUserIdentityByUserIds in the service com.mc.system.model.client.SysUserIdentityClient.

[AllKai]

When I switched to version 1.8.0 of seata-spring-boot-starter, the issue was resolved.

[funky-eyes]

你确定当时xid存在吗？ Are you sure xid existed at that time?

[funky-eyes]

我确认该问题在没有xid的情况下，branchtype返回了null，进行向下兼容io seata时，会出现npe I confirm the problem. In the absence of xid, branchtype returns null, and when backwards compatibility with io seata, npe will appear.

目前我已经降级换成了1.8.0 暂时没有出现问题

应该是没有对非分布式事务下调用时，强行转换了branchtype导致了npe的问题，我们在2.2上修复一下。 临时解决方案： 1.降级 2.我们去dubbo侧更新一下这个filter，对xid进行判空，当xid不为空再去getbranchtype 3.你可以去掉dubboseata这个filter，自行按上述逻辑重写一个
