no opentracing context value found for span context key x_b3_traceid for request [request_id]

[stackempty]

Hi,

I'm trying out opentracing with nginx-ingress-controller.

After enabling B3 using the following environment variables, the logs are filled with messages like below and the b3 headers are not being propagated.

environment vars

controller:
  extraEnvs:
  - name: DD_TRACE_PROPAGATION_STYLE_EXTRACT
    value: Datadog B3
  - name: DD_PROPAGATION_STYLE_INJECT
    value: Datadog B3
  - name: DD_AGENT_HOST
    valueFrom:
      fieldRef:
        fieldPath: status.hostIP
  - name: DD_ENV
    valueFrom:
      fieldRef:
        fieldPath: metadata.labels['tags.datadoghq.com/env']
  - name: DD_SERVICE
    valueFrom:
      fieldRef:
        fieldPath: metadata.labels['tags.datadoghq.com/service']

controller vars

controller:
  config:
    datadog-collector-host: "$DD_AGENT_HOST"
    datadog-service-name: "$DD_SERVICE"
    datadog-environment: "$DD_ENV"
    enable-opentracing: "true"
    location-snippet: |
      opentracing_trace_locations off;
      opentracing_tag resource.name $uri;
      opentracing_operation_name "$request_method $uri";
      opentracing_propagate_context;
