Description

Sometimes the call to blockchain.scripthash.listunspent returns this result:

{
   "result":[
      {
         "tx_hash":"d5e8c667080b349ef6c28d94e9d18e714bfc46a9edcd2d2473e89d8e1c2f0ea7",
         "height":1892169
      }
   ],
   "id":"76942fbf-29f4-4461-b9ca-86dda8636ce8",
   "jsonrpc":"2.0"
}

As we can see in the response, two fields tx_pos and value are missing.

Also, an empty array is often returned when utxo actually exist.

How to determine if utxo is really missing or is it wrong response?

Research direction

Start by reproducing the blockchain.scripthash.listunspent call using the response examples in the issue, then trace the server entry point that constructs this result. Compare responses for existing and missing UTXOs and inspect how tx_pos, value, and empty results are produced; done means the behavior is understood and incorrect responses are addressed with coverage for these cases.
