So Im trying to use tihs code to copy traders in pancakeswap. But when the code achive the line (how i think) let decodedData = iface.parseTransaction({ data: txInfo.data }) code doesnt do bet like a trader. Code and errror is under.


const { ethers } = require('ethers')
const dotenv = require('dotenv').config();

const privateKey = process.env.privatekey
const provider = new ethers.providers.WebSocketProvider('wss://lingering-boldest-layer.bsc.discover.quiknode.pro/b3654a959a4ba0b782f4fe539b0f5f2c2b656f0f/')
const wallet = new ethers.Wallet(privateKey)
const signer = wallet.connect(provider)


//Prediction game Contract
const predictionAddress = '0x18B2A687610328590Bc8F2e5fEdDe3b582A49cdA';  // CAKE USD

    })
}

mempool()

the error which I catch enter image description here

I expect that code will copy traders bet
