Resolution

The Data Grid ConfigListener, by mistake after the upgrade, will be similar to the below:

 containers:
        - name: infinispan-listener
          image: 'registry.redhat.io/datagrid/datagrid-8-rhel9-operator@sha256:d719d778b0848588a7e61d3c3fa689763f51a6533af4cf9e1c738c4ed8fac760'
          args:
            - listener
            - '-namespace'
            - dg-test
            - '-cluster'
            - info

The ConfigListener deployment should be similar to the following:

 containers:
        - name: infinispan-listener
          image: 'registry.redhat.io/datagrid/datagrid-8-rhel9-operator@sha256:d719d778b0848588a7e61d3c3fa689763f51a6533af4cf9e1c738c4ed8fac760'
          args:
            - listener
            - '-namespace'
            - dg-test
            - '-cluster'
