parentSegmentId question

[zou79189747]

a request pass 3 node , first node use java agent ,second node use nodejs agent， third node use java agent。but on trace page the chart is incomplete。I found the nodejs agent sent span data have a problem that the parentSegmentId in refs equal trace_id , I think parentSegmentId should be the first node sent segmentId , but it's not ,why?

Ask this at nodejs agent project. It isn't skywalking issue.

Header has two versions protocol. I don't know whether it upgraded in nodejs agent. SkyWalking java agent has compatible mode with v5 header.

Read setup document.

In Java agent the config agent.active_v2_header default is true , I want to check SkyAPM-nodejs config ,but
so many page url return 404 in SkyAPM-nodejs document ,I can't find the config list ,I create a new issue in nodejs agent project , but that project looks like inactive，I'm not sure I will get answer. And can you show me the url about v5 header

In java agent, v5 header is agent.active_v1_header. cc @ascrutae
