Invalid blockchain.scripthash.listunspent result

[dmitry537]

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?

This is the code; the result you show is not possible: https://github.com/kyuupichan/electrumx/blob/master/electrumx/server/session.py#L1083-L1096

You're either running 3rd party code, not calling blockchain.scripthash.listunspent, or have modified the code yourself.
