无论gasLimit如何，使用ethrereumjs-tx签名和使用HttpProvider发送会给出“超过区块气体限制”

Question

我正在尝试编写一个保存私钥并对事务进行签名的服务器。我使用ethereumjs-wallet/hdkey生成帐户和私钥，使用ethereumjs-tx对事务进行签名，使用Httprovider使用web3js发送事务。

不幸的是，当我尝试发送事务时，我总是收到错误消息“超过块气体限制”(即使我将gasLimit设置为21000，远远低于我的ganache-cli实例的块气体限制)。

我怀疑原始编码事务的格式是错误的。

你知道真正的问题是什么以及我如何解决它吗？

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txParams中的值需要进行十六进制编码并以0x为前缀
