Node.js sendSignedTransaction:仲裁上的发件人错误无效

我正在尝试使用一个帐户调用节点应用程序上的智能合约上的方法，该帐户是我使用私有仲裁区块链上的web3从私钥创建的。我正在使用下面的代码，但我不断收到错误“错误：返回的错误：无效发件人”。代码如下：

const Web3 = require("web3")
const web3 = new Web3(RPC_NODE);

var contract = new web3.eth.Contract(CONTRACT_ABI, CONTRACT_ADRESS);
var myMethod = contract.methods.myMethod(param1, param2);
var encodedABI = myMethod.encodeABI()

const account = web3.eth.accounts.privateKeyToAccount(PRIVATE_KEY);

var tx = {
  from: account.address,
  to: CONTRACT_ADRESS,
  gas: 2000000,
  data: encodedABI
};

console.log("Account Address:", account.address);

account.signTransaction(tx).then(signed => {
  var tran = web3.eth.sendSignedTransaction(signed.rawTransaction);
  console.log("Raw Signed Transaction:", signed.rawTransaction);
});

这个错误是有道理的，因为如果我看一下日志，我得到的是：

账户地址：0xBd55e32CB2559b06511D03E9B37a1c3bfF0f35Cd

如您所见，已签名原始事务的“发件人”字段与我使用私钥创建的帐户的地址不匹配。有人能解释一下这种行为吗？

上次我遇到类似的问题时，我很难理解私钥的格式

根据您使用的web3版本，此格式可能会影响通过

privateKeyToAccount

创建的帐户

我猜您缺少

0x

前缀。请确保您的

私钥

前面有一个

“0x”

，然后再试一次。

我通过向tx对象添加正确的

链ID解决了这个问题
