Keycloak Issue - Authentication Disabled

[shiva-rakshith]

We have set authentication_enabled to false. Getting below error when trying to create a record.

{
    "id": "sunbird-rc.registry.invite",
    "ver": "1.0",
    "ets": 1687080373637,
    "params": {
        "resmsgid": "",
        "msgid": "996271a3-ac1c-45fb-b8c0-6312798da19a",
        "err": "",
        "status": "UNSUCCESSFUL",
        "errmsg": "Exception executing consequence for rule \"Create entity owner for newly added owner fields\" in dev.sunbirdrc.workflow: [Error: keycloakAdminUtil.createUser(stateDefinition.getEntityName(), stateDefinition.getUpdated().get(\"userId\").textValue(),        stateDefinition.getUpdated().get(\"email\").textValue(), stateDefinition.getUpdated().get(\"mobile\").textValue()): RESTEASY004655: Unable to invoke request: java.net.UnknownHostException: keycloak]\n[Near : {...

    },
    "responseCode": "OK"
}

If authentication is disabled, do we still need keycloak service to be running?
