Django Elastic Beanstalk Static Configuration not working

I'm trying to deploy a Django application on Elastic Beanstalk, and had problems with my css files in the static folder generated by python3 manage.py collectstatic being read by my html templates.

I digged deeper, and turns out when I SSH into the EC2 instance that is hosting my application, the file /etc/nginx/conf.d/elasticbeanstalk/01_static.conf contains

location /static/ {
    alias /var/app/current/static;
    access_log off;
}

My application only works when I manually change this file to contain

location /static/ {
    alias /var/app/current/static/;
    access_log off;
}

The only change here is that I added a trailing slash at the end of the alias. I looked this up more, and was recommended that I create a 01_static.config file in the .ebextensions directory within the root directory, which I did and populated with the following:

files:
  "/etc/nginx/conf.d/elasticbeanstalk/01_static.conf":
    mode: "000755"
    owner: root
    group: root
    content: |
      alias /var/app/current/static/;

However, this doesn't seem to do anything. Does anyone have solutions as to how I can add the trailing slash without manually SSHing into an EC2 instance on every deployment? Thanks in advance.

You can also generate static files with container commands. Try the config files below in ebextensions.

container_commands:   01_collectstatic:
    command: "source /var/app/venv/*/bin/activate && python manage.py collectstatic --noinput"
    leader_only: true 
option_settings:   aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: YOURAPP.settings

--EDIT-- My bad I didn't understand your question. You can make custom settings for nginx using extension.

Try the following config files if you are using AL2.

option_settings:
  aws:elasticbeanstalk:environment:proxy:staticfiles:
    /static: static 

Answer from here Static files configuration in AWS not working has this setting combined with my previous answer.

If that doesn't workout, you can also try to make a custom settings for nginx.
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/platforms-linux-extend.html.

Make a custom config files under .platform/nginx/conf.d/custom.config
