GitHub Workflow Failing at Azure Login

[arana2]

Hello,

I'm following this MS Learn Exercise and running into a login issue.

Error: Login failed with Error: Using auth-type: SERVICE_PRINCIPAL. Not all values are present. Ensure 'client-id' and 'tenant-id' are supplied.. Double check if the 'auth-type' is correct. Refer to https://github.com/Azure/login#readme for more information.

I'm unsure why I'm running into this issue. I confirmed the client-id and tenant-id are stored in Github Secrets. Any help or guidance would greatly be appreciated.

Here is the workflow file.

name: Deploy ARM Template

on:
  push:
    branches:
      - main
env:
  AZURE_SUBSCRIPTION_ID: '[REDACTED]'  # set this to your Azure Subscription Id
  AZURE_RESOURCE_GROUP: GitHubActionExercise-rg   # set this to your target resource group

jobs:
  deploy-virtual-network-template:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout source code
        uses: actions/checkout@main

      - name: Login to Azure
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: Deploy ARM Template
        uses: azure/arm-deploy@v1
        with:
          scope: resourcegroup
          subscriptionId: ${{ env.AZURE_SUBSCRIPTION_ID }}
          resourceGroupName: ${{ env.AZURE_RESOURCE_GROUP }}
          template: ./azuredeploy.json
