AttributeError: 'HTTPClient' object has no attribute '_closed'

[anuj9196]

Gaffer version: gaffer version 0.5.2

I have a Django 2.0 application deployed on VPS with virtual environment setup using pipenv.

At present, using this command to run the application from terminal in background.

/root/.local/bin/pipenv run /home/user/.local/share/virtualenvs/app.application.com-IuTkL8w_/bin/gunicorn myapp.wsgi:application &

Now, I want to configure using Procfile and gaffer.

I added a file Procfile to root of the application directory with command

web: gunicorn myapp.wsgi --log-file - --log-level debug

and trying to load it with gaffer

$ cd myproject
$ gaffer load Procfile

but it is giving error as

Traceback (most recent call last):

How to solve this AttributeError: 'HTTPClient' object has no attribute '_closed' error?

I got the same issue. I tried other versions of tornado and pyuv but no luck. I ended up downgrading to gaffer v0.4.4.
