Ubuntu – GitHub Deployment of PowerShell Code to Azure Function

I’ve encountered challenges deploying my PowerShell code from GitHub to an Azure Function (consumption plan windows). The function has been deployed with Terraform and GitHub, and I aim to automate the entire deployment process through GitHub rather than locally on my machine.

The PowerShell code, located in run.ps1and other project files, needs deployment to the Azure Function. Although my workflow file completes successfully, it appears that my function is not receiving the relevant code and is empty. Comparing my function project’s directory structure in VS Code to the PowerShell developer reference, there seems to be a difference.

My project’s directory structure:

.packaged-functionsrules-backup-function
.packaged-functionsrules-backup-functionanalytical-rules-backup-function
.packaged-functionsrules-backup-function.funcignore
.packaged-functionsrules-backup-function.gitignore
.packaged-functionsrules-backup-functionhost.json
.packaged-functionsrules-backup-functionlocal.settings.json
.packaged-functionsrules-backup-functionprofile.ps1
.packaged-functionsrules-backup-functionrequirements.psd1
.packaged-functionsrules-backup-functionanalytical-rules-backup-functionfunction.json
.packaged-functionsrules-backup-functionanalytical-rules-backup-functionrun.ps1
.packaged-functionsrules-backup-functionanalytical-rules-backup-functionsample.dat

Documentation powershell function directory structure:

My GitHub workflow file:

name: Deploy Azure Function

on: workflow_dispatch

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

steps:
- name: Checkout code
  uses: actions/checkout@v2

- name: Zip folder
  run: |
    cd packaged-functions/rules-backup-function
    zip -r ../../output.zip .
  shell: bash

- name: Upload zip file
  uses: actions/upload-artifact@v2
  with:
    name: function-zip
    path: output.zip

  deploy-azure-function:
    runs-on: windows-latest
    needs: build-and-deploy
    environment: dev
    steps:
    - name: 'Checkout GitHub Action'
      uses: actions/checkout@v3

- name: 'Download zip file'
  uses: actions/download-artifact@v2
  with:
    name: function-zip
    path: .

- name: 'Run Azure Functions Action'
  uses: Azure/functions-action@v1
  with:
    app-name: ${{ secrets.AZURE_FUNCTIONAPP_NAME }}
    package: .
    publish-profile: ${{ secrets.AZURE_FUNCTIONAPP_PUBLISH_PROFILE }}

In my Azure functions there is no "function" listed:

I’ve consulted the following documentation, but the issue persists:

https://learn.microsoft.com/en-us/azure/azure-functions/functions-how-to-github-actions?tabs=windows%2Cpowershell&pivots=method-template

https://learn.microsoft.com/en-us/azure/azure-functions/deployment-zip-push

Edit 1:

I have deployed for a second time without zipping the code as a seperate step:

Workflow File:

name: Deploy PowerShell project to Azure Function App

on:  workflow_dispatch
  # [push]

env:
  AZURE_FUNCTIONAPP_PACKAGE_PATH: 'packaged-functionsrules-backup-function'       # set this to the path to your function app project, defaults to the repository root

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

    - name: 'Run Azure Functions Action'
      uses: Azure/functions-action@v1
      id: fa
      with:
        app-name: ${{ secrets.AZURE_FUNCTIONAPP_NAME }}
        package: ${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}
        publish-profile: ${{ secrets.AZURE_FUNCTIONAPP_PUBLISH_PROFILE }}

However I am getting new errrors now visible in the Azure Function, in the portal:
"Microsoft.Azure.WebJobs.Script: Did not find functions with language [dotnet]."

Runtime version: Error

And, like before the functions tab with my functions code is not visible:

This leads me to believe the configuration of my azure function is incorrect:

Or the configuration with terraform when deploying the function is incorrect:

resource "azurerm_service_plan" "analytical-rules-backup" {
  name                = "analytical-rules-backup-plan"
  resource_group_name = module.environment.resource_group_name
  location            = module.environment.location
  os_type = "Windows"
  sku_name = "Y1"
}

resource "azurerm_windows_function_app" "analytical-rules-back-function" {
  name                       = "analytical-rules-backup-function"
  resource_group_name        = module.environment.resource_group_name
  location                   = module.environment.location
  
  storage_account_name       = azurerm_storage_account.analytical-rules-backup-sa.name
  storage_account_access_key = azurerm_storage_account.analytical-rules-backup-sa.primary_access_key
  service_plan_id            = azurerm_service_plan.analytical-rules-backup.id

  site_config {}
}

Any ideas what to fix? Thank you
