[kube-prometheus-stack] template validation fails with secretkey about helm-charts HOT 1 CLOSED

serviceKey is a SecretKeySelector [0]:

The secret’s key that contains the PagerDuty service key (when using integration type “Prometheus”). Either this field or routingKey needs to be defined. The secret needs to be in the same namespace as the AlertmanagerConfig object and accessible by the Prometheus Operator.

For example:

receivers:
- name: test-pagerduty2
  pagerdutyConfigs:
  - serviceKey:
      name: mysecret
      key: servicekey

In the example, the real PagerDuty service key is stored in the key "servicekey" in secret "mysecret".
