 for _, resource := range receiver.Spec.Resources { 
 	if err := s.annotate(ctx, resource, receiver.Namespace); err != nil { 
 		logger.Error(err, fmt.Sprintf("unable to annotate resource '%s/%s.%s'", 
 			resource.Kind, resource.Name, resource.Namespace)) 
 		withErrors = true 
 	} else { 
 		logger.Info(fmt.Sprintf("resource '%s/%s.%s' annotated", 
 			resource.Kind, resource.Name, resource.Namespace)) 
 	} 
 } 

Currently my logs are showing like resource '<Kind>/<Name>.' annotated. Note the trailing dot after <Name>. It would be nice to either:

• Make that dot optional when resource.Namespace isn't defined.
• Fallback to receiver.Namespace if resource.Namespace isn't defined.
