@NuttakitDW
I have confirmed that the trace_id generated in Hotrod is present in the Jaeger UI when searched. However, the issue appears to be that the Hotrod service itself is not listed under the "Services" section, as shown in the image. Am I on the right track in assuming that the actual bug is the Hotrod service not appearing in the services list?
