与ethrereumjs-TX注册和使用HttpProvider给人发送“超出块限气”不管gasLimit的

Question

我试着写保存私钥和体征交易服务器。我用ethereumjs钱包/ hdkey生成账户和私有密钥，ethereumjs-TX签署交易，并用Httprovider发送交易web3js。

不幸的是，当我尝试发送交易，我总是得到错误信息“超出块限气”（即使我我gasLimit设置为21000，远低于我的伽纳彻-CLI实例的块气体限制）。

我怀疑原始编码的交易被错误地形成。

任何想法实际的问题是什么，如何解决呢？

干杯

const hdkey = require('ethereumjs-wallet/hdkey');
const Transaction = require('ethereumjs-tx');
const walletHdpath = "m/44'/60'/0'/0/";
const hdwallet = hdkey.fromMasterSeed(bip39.mnemonicToSeed(process.env.KEYSTORE_SEED));
const web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

async function generateAccount() {
        const wallet = hdwallet.derivePath(walletHdpath + nextAccountIndex).getWallet();
        nextAccountIndex += 1;
        const addr = '0x' + wallet.getAddress().toString('hex');
        accounts[addr] = wallet;

        await fundAccount(addr);

        return addr;
}

async function fundAccount(address) {
    const txParams = {
        gasPrice: '20000000000',
        gasLimit: '21000',
        from: process.env.KEYSTORE_ADDRESS_0,
        to: address,
        value: web3.utils.toWei('0.1', 'ether'),
        data: ''
      }

      const signed = signTransaction(txParams);

      // this line throws exception: "exceeds block gas limit"
      await web3.eth.sendSignedTransaction(signed.signed_transaction);
}

function signTransaction(txParams) {
    const from = txParams.from.toLowerCase();
    const wallet = accounts[from];
    if (wallet === undefined) {
        return {sucess: false, message: "unknown from account" }
    } 

    const tx = new Transaction(txParams);
    const pkey = wallet.getPrivateKey();
    tx.sign(pkey);
    const rawTx = '0x' + tx.serialize().toString('hex');

    return { success: true, signed_transaction: rawTx }
}

问题是，在txParams的值需要十六进制编码，并以0x前缀
