A query like:

query {
  getMarketDataHistoryConnectionByID(
    id:"5d69ff4a485a9f963272c8614c1d0d84bb8ea57886f5b11aad53f0ccc77731ba"
  	start:"2023-01-31T10:22:00Z"
  	end: "2023-01-31T10:23:02Z"){
	edges{
    node{
      priceMonitoringBounds {
        trigger {
          horizonSecs
          probability
          auctionExtensionSecs
        }
        minValidPrice
        maxValidPrice
        referencePrice
      } 
    }
  }
  }
}

Returns 0s for minValidPrice, maxValidPrice, referencePrice. A corresponding subscription works fine.
