比特币交易的串行化错误

Question

当我将比特币一个附件发送到另一个：版本的npm“位核心-探索者”："^1.0.1"，“位核心-库”："^8.22.2“时，会出现序列化错误。

const explorers=require('bitcore-explorers')
var insight=new explorers.Insight();
var bitcore = require('bitcore-explorers/node_modules/bitcore-lib');
var privateKeyWIF='L4xkFv5sbttQcsgnTjzqJuQdNfHC5gk9zsK5HmaV822qu79zJA7L';
var privateKey = bitcore.PrivateKey.fromWIF(privateKeyWIF);
var sourceAddress = privateKey.toAddress();
var targetAddress = '1HgaQXpi9GC57zCPd1X8NHkPJaizEh6g8N'
insight.getUnspentUtxos(sourceAddress, function (error, utxos) {
  if (error) {
    console.log(error);
  } else {
    console.log(utxos);
    var tx = new bitcore.Transaction();
    tx.from(utxos);
    tx.to(targetAddress, 10000);
    tx.change(sourceAddress);
    tx.fee(50000)
    tx.sign(privateKey);
    console.log(tx.serialize());
    insight.broadcast(tx, function (error, transactionId) {
      if (error) {
        console.log("hii3")
        console.log(error);
      } else {
        console.log("hiii4")
        console.log(transactionId);
      }
    });
  }
});

bitcore使用bitpay作为默认的提供程序服务器，由于某种原因，它无法工作。他们还建议更改文档中的默认服务器。尝试将提供程序更改为zelcore，如下所示：

const explorers = require("bitcore-explorers");
const insight = new explorers.Insight("https://explorer.btc.zelcore.io");
