I'm confused with the following code. I have tried to figure out why need to strip rlp-encoded beginning bytes, but failed. Wish for your detail !!!

https://github.com/metachris/flashbotsrpc/blob/master/flashbotsrpc.go#L681

	// Might need to strip beginning bytes
	if rlp[:2] == "b9" {
		rlp = rlp[6:]
	} else if rlp[:2] == "b8" {
		rlp = rlp[4:]
	}

hi, metachris, glad to see you share this package, I am able to wrap up a legacy tx and send mev successfully but when I try to wrap up an EIP1559 tx, the response always shows unable to decode tx I am wondering if this package currently supports EIP1559 txn?

I am getting list of ts and then calling rpc method eth_sendbundle. But flashbot server is not able to parse it.

       // generate the transact opts
       	topts, err := bind.NewKeyedTransactorWithChainID(wallet.PrivateKey, big.NewInt(cfg.ChainId))
	log.CheckFatal(err)
	topts.NoSend = true
	topts.GasLimit = 10000000
//  array of the txs
        txs := []string{}
	tx, err := erc20.Transfer(topts, to, amount)
	log.CheckFatal(err)
	txBytes := &bytes.Buffer{}

	err = tx.EncodeRLP(txBytes)
	log.CheckFatal(err)
	txs = append(txs, "0x"+hex.EncodeToString(txBytes.Bytes()))
// generate the bundle
	sendBundleArgs := flashbotsrpc.FlashbotsSendBundleRequest{
		Txs:         txs,
		BlockNumber: fmt.Sprintf("0x%x", blockNum),
	}
	var sigKey, _ = crypto.GenerateKey()
	result, err := p.RPC.FlashbotsSendBundle(sigKey, sendBundleArgs)
// check error
	if err != nil {
		if errors.Is(err, flashbotsrpc.ErrRelayErrorResponse) {
			// ErrRelayErrorResponse means it's a standard Flashbots relay error response, so probably a user error, rather than JSON or network error
			log.Error(err.Error())
		}
	}

Can you tell not I am doing wrong, plz?

Error:

relay error response: unable to decode bundle
