Issue while configuring slack contact points

I have created a slack contact point using Grafana Operator

apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaContactPoint
metadata:
  name: slack-contact-point
  namespace: grafana
spec:
  instanceSelector:
    matchLabels:
      dashboards: "grafana"
  name: "Slack Contact"
  type: slack
  settings:
    recipient: "#argocd"
    username: "Grafana"
    icon_emoji: ":grafana:"
    token: ""
  valuesFrom:
    - targetPath: token
      valueFrom:
        secretKeyRef:
          name: credentials
          key: SLACK_TOKEN

This creates a slack contact point in grafana.

But when I try to test notification delivery I get this error.

Logs from grafana instance:

logger=ngalert.notifier.slack notifierUID=0cf3251e-23df-4464-b9f6-7c06af020de9 t=2025-12-23T22:32:28.607966088Z level=error msg="Missing receiver"

When I do this manually using UI. It is working as expected.

And when I use this config:

    valuesFrom:
    - targetPath: settings.token
      valueFrom:
        secretKeyRef:
          key: SLACK_TOKEN
          name: credentials

I am getting this error:
