Startup.sh not found

Question

I'm trying to deploy a simple django app.

When I deploy it vanilla (i.e. use Azure extension on VSCode) and deploy it, it does not seem to do any collectstatic, and as a result whitenoise complains all the files aren't found.

So I think I need to create a startup.sh like this to be able to run collectstatic, as well as migrations:

#!/bin/bash
# run collectstatic
pip install --upgrade pip
pip install -r requirements.txt

npm installnpm run build

python manage.py collectstatic --noinput

python manage.py makemigrationspython
manage.py migrate

gunicorn --bind 0.0.0.0 --workers 1 --threads 8 --timeout 600 myappmodule.wsgi:application

I named it startup.sh and put it in my root directory of my project. Also gave it chmod +x and permissions look good. -rwxr-xr-x

I then specified the startup command to be startup.sh

I tried it both via the general settings > startup command, and I tried it also in

az webapp config set --name $APPNAME --resource-group $RESOURCEGROUP --startup-file "startup.sh"

But I keep running into this:

2023-07-09T19:27:53.203141399Z /opt/startup/startup.sh: 23: /opt/startup/startup.sh: startup.sh: not found

Been trying to deploy for a week now and keep getting stuck; hoping for any help.

I did the stack overflow thing of substituting the newlines and also tried to rename it to something else (to mystartup.sh), because it seems like there's another startup.sh inside /opt/startup. But it just complains that mystartup.sh isn't found in that case.
