我调用了硬件的签名成功签名，但是无法将交易广播出去

我想要实现的功能是通过硬件钱包生成ETH网络的地址，通过 HardwareSDK.evmSignTransaction接口获得交易签名，然后广播交易完成转账，转账的网络是BSC;我现在已经正常的唤醒Onekey的硬件，获得了签名数据，但是无法完成广播交易，使用官方示例中的广播也无法正常发送广播交易

// 1. Create transaction parameters
const txParams = {

// gasPrice: '0x14', //
};

// 2. Sign the transaction
const result = await HardwareSDK.evmSignTransaction(connectId, deviceId, {
path: "m/44'/60'/0'",
transaction: txParams,
...deviceCommonParams
});

// 3. Build signed transaction
const baseTx = {
to: txParams.to,
nonce: parseInt(txParams.nonce, 16),
gasLimit: txParams.gasLimit
data: txParams.data,
value: txParams.value,
chainId: txParams.chainId,

// Add EIP-1559 specific fields
const isEIP1559 = txParams?.maxFeePerGas || txParams?.maxPriorityFeePerGas;
if (isEIP1559) {
Object.assign(baseTx, {
type: TransactionTypes.eip1559,
maxFeePerGas: txParams?.maxFeePerGas
maxPriorityFeePerGas: txParams?.maxPriorityFeePerGas
});
} else {
Object.assign(baseTx, {
gasPrice: txParams.gasPrice,
});
}

// 4. Build final transaction with signature
const { rawTx, txid } = buildSignedTxFromSignatureEvm({
tx: baseTx,
signature: result.payload
});

这是官方的示例代码，但是里面的splitSignature没有声明，导致无法正常运行
