Error generating Swagger server (Python Flask) from Swagger editor
<p>I've used the Swagger Editor to manually generate my Swagger spec file and generated the files for a Python Flask server. Following the README I installed connexion, but when I run <code>python app.py</code> I get the error: 
ValueError: need more than 1 value to unpack. Any ideas?</p>

<p>Full stack trace below:</p>

<pre><code>No handlers could be found for logger "connexion.api"
