Falcon app with Instana WSGI middleware

myfalcon.py

import falcon
import instana
from instana.wsgi import iWSGIMiddleware
instana.service_name = "Falcon_Service"

# Falcon follows the REST architectural style, meaning (among
# other things) that you think in terms of resources and state
# transitions, which map to HTTP verbs.


class ThingsResource(object):
    def on_get(self, req, resp):
        """Handles GET requests"""
        resp.status = falcon.HTTP_200  # This is the default status
        resp.body = ('\nTwo things awe me most, the starry sky Its the end of hte world as we know it'
                     'above me and the moral law within me.\n'
                     '\n'
                     '    ~ Immanuel Kant\n\n')


# falcon.API instances are callable WSGI apps
app = falcon.API()

# Resources are represented by long-lived class instances
things = ThingsResource()

# things will handle all requests to the '/things' URL path
app.add_route('/things', things)

app = iWSGIMiddleware(app)

These are my ENV variables. I am still not getting traces.
#!/usr/bin/env bash
export INSTANA_DEV=true
export AUTOWRAPT_BOOTSTRAP=instana
export INSTANA_SERVICE_NAME=FalconService

Do you think we have different versions of the Python Sensor ?

Here is a link to the running application. I have request hitting it every 5 minutes and no traces are showing up.
