Thank you. That helped! silly me. I do get a math error ValueError now: ``` website_1 | File "/usr/local/lib/python3.6/site-packages/flask_split/templates/split/index.html", line 9, in block "content" website_1 | {% include "split/_experiment.html" %}...

Having this issue as well with gunicorn 19.9.0 and Flask-socketIO 3.0.2, when using eventlet 0.24.1 > AttributeError: 'Response' object has no attribute 'status_code'

It looks like this issue has been fixed in the latest version of [python-engineio](https://pypi.org/project/python-engineio/2.3.2/)..
