When I reproduce the bare version (no istio or linkerd), the log of web-svc is a little strange for me

The similar situation happend in the istio version,

Is this expected?

Does the wrk2 pod report any HTTP error codes or socket errors after the run?

There is no any HTTP error codes or socket errors after the run. I think this is expected. But I still edit the wrk2.yaml.tmpl to avoid using api/list

        - "http://web-svc-1.emojivoto.svc.cluster.local:8080"
        - "web-svc-1"
        - "${INSTANCES}"
        # - "api/list
        - "api/vote?choice=:flushed:"
        - "api/vote?choice=:policeman:"
        - "api/leaderboard"
