argocd notifications controller logs error when trying to send a notification using new workflow webhooks from microsoft

[shinsu777]

I've been trying to switch to the new workflow webhooks from microsoft as they won't be supported at the end of 2025 anymore.
The notifications are working completely fine as intended with the old webhooks, but these new workflow webhooks don't work. Not sure if they aren't supporting the adaptive card which is being sent by the notifications controller or if it's something else.

I have deployed argocd via the argocd helmchart (chart version: argo-cd-7.7.0 app version: v2.13.0) and my notifications controller pod logs the following:

level=error msg="failed to execute when condition: cannot fetch phase from <nil> (1:27)\n | app.status.operationState.phase in ['Succeeded'] and app.status.health.status == 'Healthy'\n | ..........................^"
level=error msg="Failed to notify recipient {teams teamsDevopsArgoCd} defined in resource argo-cd/my-application: teams webhook post error: using the configuration in namespace argo-cd" resource=argo-cd/my-application

My values.yaml for the helm chart looks like this:

notifications:
  enabled: true

  secret:
    create: true

    items:
      devops-argocd-teams-url: $my-webhook-url
