Function app deployment causes internal server error

[austinh123123]

Hello, I have a python 3.9 function app. I tried to automate its deployment with this action, only to be met with internal server errors or CORS errors after deployment. The curious this is; I can deploy with the VScode extension and all the code runs fine. I'm not sure if I have an error in configuration.
For reference, I've added the action yaml, host.json, and function.json (there's only one function).
deploy.yaml:

name: Deploy python function app to Azure Function App

on:
push:
branches:
- master
env:
AZURE_FUNCTIONAPP_NAME: 'APP_NAME' # I set this but changed it in for the issue
AZURE_FUNCTIONAPP_PACKAGE_PATH: '' # set this to the path to your function app project, defaults to the repository root

jobs:
build-and-deploy:
runs-on: ubuntu-latest
environment: dev

- name: 'Checkout GitHub Action'
uses: actions/checkout@v3
- name: Setup Python 3.9 Environment

shell: bash

pushd './${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}'
python -m pip install --upgrade pip
pip install -r requirements.txt --target=".python_packages/lib/site-packages"

function.json:
