Conéctese ya ejecutando bitcoind con bitcore para bitcoin explorer

Quiero crear un explorador de bitcoin usando bitcoind. Estoy usando bitcore e insight API para este propósito.

Ya estoy ejecutando bitcoind en mi sistema local. Quiero conectar este bitcoind en ejecución con bitcore y usar insight-api y UI.

este es mi archivo bitcore-node.json :

{
  "network": "testnet",
  "port": 3001,
  "services": [
    "bitcoind",
    "insight-api",
    "insight-ui",
    "web"
  ],
  "servicesConfig": {
    "bitcoind": {
      "spawn": {
        "datadir": "./",
        "exec": "/home/ajit/.nvm/versions/node/v4.8.6/lib/node_modules/bitcore/node_modules/bitcore-node/bin/bitcoind"
      }
    }
  }
}

He copiado y pegado node_moduleen bitcore-node.jsonla .bitcoincarpeta donde los bloques de bitcoin ya están descargados y actualizados.

este es mi bitcoin.conf

server=1
testnet=1
whitelist=127.0.0.1
txindex=1
addressindex=1
timestampindex=1
spentindex=1
zmqpubrawtx=tcp://127.0.0.1:28332
zmqpubhashblock=tcp://127.0.0.1:28332
rpcallowip=127.0.0.1
uacomment=bitcore

cuando ejecuto bitcore obtengo estos registros

Cuando abro insight-UI. se abre la interfaz de usuario, obtuve algunas transacciones pero no obtuve la lista de bloques y dentro de 10 segundos bitcore se detiene con este registro
