Chart installation fails when watchNamespace includes the helm release namespace due to duplicate RoleBindings

[mihirbhagwat0]

Helm chart fails to install when the watchNamespace parameter contains the same namespace as the Helm release namespace. It tries to create a RoleBinding object for that namespace twice, causing the installation to fail.

Expected Behavior

The Helm chart should create a RoleBinding only once per namespace, even if the release namespace is included in watchNamespace.

Actual Behavior

The chart tries to create two RoleBinding objects for the same namespace, causing the installation to fail.

Steps to Reproduce the Problem

1. Set the Helm release namespace to test
2. Set the watchNamespace parameter to test
3. helm install keda kedacore/keda --namespace test --set watchNamespace=test

Specifications

• KEDA Version: 2.16.1
• Platform & Version: 2.16.1
• Kubernetes Version: 1.31.6
