Bug: Azure/k8s-deploy@v4 doesn't seem to be working after upgrading to AKS 1.24.9

[ealasgarov]

What happened?

I have upgraded my private cluster to latest stable version 1.24.9, since then cannot get the pipeline to work. (although I'm also using the new service principle [azure credentials], new clusterrole/binding for that service principle, but I guess here there are no issues).
I have deployed in this way previously with no problems, but now getting "error undefined" upon deploy step.

Here's my pipeline:

name: deploy-test
on: workflow_dispatch
jobs:
  deploy:
    runs-on: platform-aks-runner
    steps:
      - name: Checkout source code 
        uses: actions/checkout@v3
      - name: Set up kubelogin for non-interactive login
        run: |
          sudo rm -f /usr/local/bin/kubelogin
          curl -LO https://github.com/Azure/kubelogin/releases/download/v0.0.28/kubelogin-linux-amd64.zip
          sudo unzip -j kubelogin-linux-amd64.zip -d /usr/local/bin
          rm -f kubelogin-linux-amd64.zip
          kubelogin --version
      - name: Azure login
        id: login
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS_DEV }}
      - name: Set AKS context
        id: set-context
        uses: azure/aks-set-context@v3
        with:
          resource-group: '${{ secrets.RESOURCE_GROUP_DEV }}' 
          cluster-name: '${{ secrets.CLUSTER_DEV }}'
          admin: 'false'
          use-kubelogin: 'true'
      - name: Setup kubectl
        id: install-kubectl
        uses: azure/setup-kubectl@v3
      - name: Deploy to AKS
        id: deploy-aks
        uses: Azure/k8s-deploy@v4
        with:
          resource-group: '${{ secrets.RESOURCE_GROUP_DEV }}' 
          name: '${{ secrets.CLUSTER_DEV }}'
          private-cluster: true 
          action: deploy
          force: true
          strategy: basic
          namespace: 'mynamespace'
          manifests: |
             ./resources.yaml
          images: '${{ secrets.registry_dev }}.azurecr.io/myrepo/myimage:latest'

I am not sure what else could be an issue. I think if the problem was with credentials I would get a different error. @OliverMKing Any ideas perhaps? Many thanks in advance!
