Describe the Problem

I wanna swap tokens using pancakeSwap router.
But an error occur and I can't understand the reason.

all code is here https://github.com/trmti/WeeklyBot2 .

config.json

{
  "minTokenPrice": 0,
  "gasPrice": "5",
  "gasLimit": 100000,
  "tokens": {
    "tokenA": "0xfb62AE373acA027177D1c18Ee0862817f9080d08",
    "tokenB": "0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56"
  }
}

swap.js

const router_address = '0x10ED43C718714eb63d5aA57B78B54704E256024E';

                ...

async function swapAllToken(account, tokenA, tokenB) {

                ...

    const router = new ethers.Contract(
      router_address,
      [
        'function getAmountsOut(uint amountIn, address[] memory path) public view returns (uint[] memory amounts)',
        'function swapExactTokensForTokens(uint amountIn, uint amountOutMin, address[] calldata path, address to, uint deadline) external returns (uint[] memory amounts)',
      ],
      account
    );

                ...

    tx = await tokenA_contract.functions.balanceOf(account.address);
    const amountIn = tx[0].sub(tx[0].div(100));
    const amounts = await router.getAmountsOut(amountIn, [tokenA, tokenB]);
    const amountOutMin = amounts[1].sub(amounts[1].div(10));
    console.log(`
      Buying new token
      =================
      tokenIn: ${(amountIn / 10 ** 18).toString()} ${tokenA}
      tokenOut: ${(amountOutMin / 10 ** 18).toString()} ${tokenB}
    `);
    tx = await router.swapExactTokensForTokens(
      amountIn,
      amountOutMin,
      [tokenA, tokenB],
      account.address,
      Date.now() + 1000 * 60 * 10, //10 minutes
      {
        gasPrice: ethers.utils.parseUnits(gasPrice, 'gwei').toString(),
        gasLimit: gasLimit,
      }
    );

bot.js

const ethers = require('ethers');
const abi = require('./bot.json');
const { swapAllToken } = require('./swap.js');
const { myWallet, secretKey, nodes } = require('../BasicConfig.my.json');
const { tokens } = require('./config.json');

const provider = new ethers.providers.JsonRpcProvider(nodes[1], {
  name: 'binance',
  chainId: 0x38,
});

const wallet = new ethers.Wallet(secretKey);
const account = wallet.connect(provider);

const contract = new ethers.Contract(tokens.tokenA, abi, provider);
const filter = contract.filters.Transfer(null, myWallet);

swapAllToken(account, tokens.tokenA, tokens.tokenB);
contract.on(filter, () => {
  console.log('You got New asset!');
});

router.swapExactTokensForTokens(
      amountIn,
      amountOutMin,
      [tokenA, tokenB],
      account.address,
      Date.now() + 1000 * 60 * 10, //10 minutes
      {
