swap - 什么理由？我有这样的错误“处理响应错误”

Question

我将使用 ether js 交换 2 个 BSC 令牌。但我有这样的错误。这是我的代码。

`const address = [tokenIn, tokenOut]; const to = config[config.network].addresses.recipient;

try {
  const wbnb_abi = [
    'function approve(address spender, uint256 amount) external returns (bool)'
  ];

  let iface = new ethers.utils.Interface(wbnb_abi);
  var data = iface.encodeFunctionData('approve', [config[config.network].addresses.router, ethers.BigNumber.from("115792089237316195423570985008687907853269984665640564039457584007913129639935")]);
  
  const txObj =
  {
    from: config[config.network].addresses.recipient,
    to: tokenIn,
    value: 0,
    gasLimit: 144264, // 100000
    gasPrice: gas_price,
    data: data
  }

  try {
    account.sendTransaction(txObj).then((transaction) => {

      let iface = new ethers.utils.Interface(pancake_route_abi);

      var data = iface.encodeFunctionData('swapExactTokensForTokens', [amountIn, amountOut, address, to, Date.now() + 1000 * 60 * 5]);

      const txObj =
      {
        from: config[config.network].addresses.recipient,
        to: config[config.network].addresses.router,
        value: 0,
        gasLimit: 144264, // 100000
        gasPrice: gas_price, // 7000000000
        data: data
      }

      try {
        account.sendTransaction(txObj).then((transaction) => {

        });
      } catch (error) {
        console.log("failed to send!!");
      }
    });
  } catch (error) {
    console.log("failed to send!!");
  }
} catch (err) {
  console.log(err)
}`

我不知道为什么会有这样的理由。帮我。
