Jaeger traceID in response headers

I'm playing with JaegerTracing in Django using tutorial https://github.com/contino/jaeger-django-docker-tutorial. Now I don't know how to take out traceId from response headers because it's not there.

When finding traces in Jaeger UI it returns response with data (see also screenshot below):

{
    "data": [{
        "traceID": "885bef8bbc18649c",
        "spans": [{

                }, {

                    "type": "string",
                    "value": "172.23.0.3"
                }, {

                    "type": "string",

                }]
            }
        },
        "warnings": null
    }],
    "total": 0,
    "limit": 0,
    "offset": 0,
    "errors": null
}

I suspected it in response headers but it is not.

How can I do this?

Solution

Found out how. I just added one single line of code into tracing.py of django_opentracing lib:

And the result:
