uwsgi fails to serve Django from a .ini file

Question

Steps to reproduce:

mkdir django-uwsgi
cd django-uwsgi
python -m venv venv
source venv/bin/activate
pip install Django uwsgi
django-admin startproject mysite
cd mysite
python manage.py migrate

Try to serve django locally with uwsgi via command line:

uwsgi --module mysite.wsgi --http :8000

Result: it works! YES!

Now, create a uwsgi.ini file with the following content:

[uwsgi]
module                = mysite.wsgi
http                  = :8000

then use uwsgi --ini uwsgi.ini

Result

ModuleNotFoundError: No module named 'mysite.wsgi # define the django module to use'

OK... So we need something else...

Try adding the current directory...

chdir                 = {WORKSPACE}/django-uwsgi/mysite

YES? Result:

ModuleNotFoundError: No module named 'mysite.wsgi # define the django module to use'

Try specifying the virtualenv. Result:

virtualenv            = {WORKSPACE}/django-uwsgi/venv
# or, or both
home                  = {WORKSPACE}/django-uwsgi/venv

YES? Result:

ModuleNotFoundError: No module named 'mysite.wsgi # define the django module to use'

Here is a full tracebakc:

Note that I use pyenv:

lrwxrwxrwx 1 loicgasser loicgasser       49 Jul 16 14:41 python -> /home/loicgasser/.pyenv/versions/3.8.3/bin/python
lrwxrwxrwx 1 loicgasser loicgasser        6 Jul 16 14:41 python3 -> python

I have been stuck for a while now... Any help would be appreciated.

Here is the configuration which is working for me. The chdir should be the directory where manage.py exists so that when you mention wsgi-file it goes to the file from that path on. also provide complete path to your virtualenv

[uwsgi]
http  = 0.0.0.0:9999
virtualenv =/path/to/djangapp/env
chdir = /path/to/djangapp -- this is where manage.py exists
wsgi-file = djangapp/wsgi.py --wsgi file path from above path
processes = 4
threads = 2
vacuum = True
harakiri=20
stats = 0.0.0.0:8000
daemonize = /path/to/djangapp/logs/CustomerCare-@(exec://date +%%Y-%%m-%%d).log
log-reopen = true
