Deploying Azure function with Github Actions fails without providing clear reason

I am trying to deploy an Azure function with Github Actions, using the standard code from Microsoft docs with only a minor adjustment to use SSH with pip:

env:
  AZURE_FUNCTIONAPP_NAME: 'func-app-name'
  AZURE_FUNCTIONAPP_PACKAGE_PATH: '.'         # set this to the path to your function app project, defaults to the repository root
  PYTHON_VERSION: '3.11'                      # set this to the python version to use (e.g. '3.6', '3.7', '3.8')

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    environment: dev
    steps:
    - name: 'Checkout GitHub Action'
      uses: actions/checkout@v3

    - name: Setup Python ${{ env.PYTHON_VERSION }} Environment
      uses: actions/setup-python@v4
      with:
        python-version: ${{ env.PYTHON_VERSION }}

    - name: Install SSH key  # extra step
      uses: webfactory/ssh-agent@v0.9.0
      with:
          ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}

    - name: 'Resolve Project Dependencies Using Pip'
      shell: bash
      run: |
        pushd './${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}'
        python -m pip install --upgrade pip
        pip install -r requirements.txt --target=".python_packages/lib/site-packages"
        popd

    - name: 'Run Azure Functions Action'
      uses: Azure/functions-action@v1
      id: fa
      with:
        app-name: ${{ env.AZURE_FUNCTIONAPP_NAME }}
        package: ${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}
        publish-profile: ${{ secrets.AZURE_FUNCTIONAPP_PUBLISH_PROFILE }}
        scm-do-build-during-deployment: true
        enable-oryx-build: true

The deployment step fails. No clear reason is provided in the logs:

Error: Deployment Failed!

The deployments works fine if I do it from my local machine with:

func azure functionapp publish "func-app-name"

What could be the problem here?

To resolve the error, add the application setting WEBSITE_RUN_FROM_PACKAGE = 1 under FunctionApp=>Configuration=>Environment Variables=>App Settings.

This setting helps to run the GitHub actions correctly and deploys the function App without any errors.

The error Failed to use /home/runner/work/_temp/temp_web_package_***.zip as ZipDeploy content in the workflow indicates that the deployment of the ZIP package to Azure App Service failed, especially the failure occurs when Azure tries to use the ZIP file.

When ZIP deployment fails, the go to approach is to use the Website_Run_from_package setting. It skips all the issues with the extraction process and directly mounts the ZIP file content avoiding the extraction.
