By pre-merge testing with the PR, figured out the root cause of failure case TestOperatorMetrics/metrics_ingested_in_Prometheus.

2025-12-04T06:29:09Z	ERROR	Reconciler error	{"controller": "observability-operator", "controllerGroup": "", "controllerKind": "Service", "Service": {"name":"observability-operator","namespace":"coo"}, "namespace": "coo", "name": "observability-operator", "reconcileID": "4d1d14b1-ff17-42a5-a59b-6822d7d47eca", "error": "coo/observability-operator (monitoring.coreos.com/v1, Kind=ServiceMonitor): updater failed to patch: ServiceMonitor.monitoring.coreos.com \"observability-operator\" is invalid: spec.endpoints[0].scheme: Unsupported value: \"HTTP\": supported values: \"http\", \"https\""}

From the above operator error log, may need perform the following change

• Scheme: ptr.To(monv1.SchemeHTTP),

• Scheme: ptr.To(monv1.Scheme("http")),

Files Modified:

• pkg/controllers/operator/components.go:48
• pkg/controllers/uiplugin/health_analyzer.go:200

[jan--f]

• Scheme: ptr.To(monv1.SchemeHTTP),

• Scheme: ptr.To(monv1.Scheme("http")),

Afaiu using the contstant monv1.SchemeHTTP should work the same 🤔

I think that only the v0.87.0 CRDs will support both "http" and "HTTP". Older CRDs only allow "http".
