@btafur  That helped, the issue is fixed now. Thanks. 

a follow up question, can we give 2 values there for cluster type, something like this

"cluster_type": {
    "type": "fixed",
    "value": "dlt"
  },
"cluster_type": { 
    "type": "fixed", 
    "value": "job" 
}

or comma separated values.

Thanks again!
