Entity operator is failing to watch multiple namespaces

Issue

• When I deploy kafka cluster, with the definition for entity operator to watch multiple namespaces, I get the below error.

Failure executing: POST at: https://IP/apis/rbac.authorization.k8s.io/v1/namespaces/ns-1,ns-2/rolebindings. Message: namespaces "ns-1,ns-2" not found. Received status: Status(apiVersion=v1, code=404, details=StatusDetails(causes=[], group=null, kind=namespaces, name=ns-1,ns-2, retryAfterSeconds=null, uid=null, additionalProperties={}), kind=Status, message=namespaces "ns-1,ns-2" not found, metadata=ListMeta(_continue=null, remainingItemCount=null, resourceVersion=null, selfLink=null, additionalProperties={}), reason=NotFound, status=Failure,

• where "ns-1" and "ns-2" are the namespaces being watched by entity operator.
• Also, when I deploy the kafka to watch single namespace individually it works.
• In Kafka resource yaml, following are the configuration

entityOperator:
    topicOperator: 
      watchedNamespace: ns-1,ns-2
      reconciliationIntervalSeconds: 60
      logging: 
        type: inline
        loggers:
          rootLogger.level: "INFO"
    userOperator: 
      watchedNamespace: ns-1,ns-2
      reconciliationIntervalSeconds: 60
      logging: 
        type: inline
        loggers:
          rootLogger.level: INFO
