The Service Graph cannot draw the call relationships between services

[QuanZi123]

I started two applications: my_app2 and my_app, and when I make a request, my_app2 calls my_app's interface
The whole call relationship looks like this: http-client -> my_app2 -> my_app, but no my_app content is plotted in the Service Graph module

Here is the traces

Is that the design, or does the logic for building the service graph need fixing
