Jaeger ui cannot display workflow trace info

I try to execute ctxpropagation, and I have run a jaeger instance. But I cannot see anything about tracing after executed workflow. Have I missed something? What shoud I do Next?Thanks a lot!

Hi, was able to get this to show on Jaeger without sample code changes:

Here is the jaeger service config in docker compose i used if that helps:

jaeger-all-in-one:
    image: jaegertracing/all-in-one:1.39
    ports:
      - "14269"
      - "14268:14268"
      - "14267"
      - "14250"
      - "9411:9411"
      - "16686:16686"
      - "16687"
      - "6831:6831/udp"
      - "6832:6832/udp"
      - "5778:5778"
    environment:
      - COLLECTOR_ZIPKIN_HTTP_PORT=9411
      - LOG_LEVEL=debug
