looks like we can use finalizingFieldAccess to solve this issue,
changing the postAggregations part into:
"postAggregations": [
{"type": "arithmetic", "name": "click_through_rate", "fn": "/", "fields":[
{"type" : "finalizingFieldAccess", "name" : "unique_click_visitors ", "fieldName" : "unique_click_visitors " },
{"type" : "finalizingFieldAccess", "name" : "unique_view_visitors ", "fieldName" : "unique_view_visitors "}
]
}
]
