Issue getting django celery worker started on elastic-beanstalk - django

Question

I am trying to get my celery worker running on elastic-beanstalk. It works fine locally but when I deploy to EB I get the error "Activity execution failed, because: /usr/bin/env: bash": No such file or directory". I am pretty novice at celery and EB so I haven't been able to find a solution so far.
I am working on a windows machine and I have seen other people face this issue with windows and fix it by converting "celery_configuration.txt" file to UNIX EOL, however I am using celery-worker.sh instead but I converted it to a UNIX EOL which still didn't work.

# Create the celery supervisord conf script
echo "$celeryconf" | tee /opt/python/etc/celery.conf
# Add configuration script to supervisord conf (if not there already)
if ! grep -Fxq "[include]" /opt/python/etc/supervisord.conf
then
echo "[include]" | tee -a /opt/python/etc/supervisord.conf
echo "files: celery.conf" | tee -a /opt/python/etc/supervisord.conf
fi
# Reread the supervisord config
/usr/local/bin/supervisorctl -c /opt/python/etc/supervisord.conf reread
# Update supervisord in cache without restarting all services
/usr/local/bin/supervisorctl -c /opt/python/etc/supervisord.conf update
# Start/Restart celeryd through supervisord
/usr/local/bin/supervisorctl -c /opt/python/etc/supervisord.conf restart celeryd-worker
I'm sure its something simple I missed but I have spent hours looking everywhere for a solution and at this point i'm out of ideas.

The issue is with your shebang (the #!/usr/bin/env bash) line in your celery-worker.sh file try using either /bin/bash or /bin/sh. Where bash or sh live will depend a lot on which AMI you are using with beanstalk.
