I’ve positioned collectively a uncooked tx hex however when it is unable to be broadcasted as I maintain getting an error under
sendrawtransaction RPC error: {"code":-25,"message":"bad-txns-inputs-missingorspent"}
I then decoded the tx hex utilizing https://reside.blockcypher.com/btc/decodetx/ to see that I appear to be lacking the Witness subject as I’m utilizing native segwit addresses:

I then thought maybe I did not add a scriptPubKey
into the addInput
however this code did not appear to work for me:
const fetch = require("node-fetch")
const bitcoin = require("bitcoinjs-lib")
const url = "https://blockchain.information/rawaddr/"
let MAINNET = bitcoin.networks.bitcoin
pubAdd = "bc1qj3rjxzhlqm6fqesd5fwphjnf457zkww3s5qrv5"
let txb = new bitcoin.TransactionBuilder(MAINNET)
var txid = null
var outn = 0
var transactionhex = ""
async operate getPubAddInfo() {
const response = await fetch(url + pubAdd)
const knowledge = await response.json()
txid = knowledge["txs"][0]["hash"]
outn = knowledge["txs"][0]["out"][0]["n"]
}
async operate getTXHash() {
await getPubAddInfo()
let WIF = "xxxxxxxxxxxx"
let keypairSpend = bitcoin.ECPair.fromWIF(WIF, MAINNET)
var scriptPubkey = bitcoin.script.witnessPubKeyHash.output.encode(bitcoin.crypto.hash160(keypairSpend.getPublicKeyBuffer()))
txb.addInput(txid, outn, null, scriptPubkey)
txb.addOutput("bc1qjp3cch0hdvdr0hy99cs76kl9kekmuxv3k9nr6l", 60000)
txb.signal(0, keypairSpend, null, null, 60200)
let tx = txb.construct()
transactionhex = tx.toHex()
console.log(transactionhex)
}
getTXHash()
For the time being I get the error TypeError: Can't learn property 'output' of undefined
on the road the place i create var scriptPubKey
.
Any recommendations as to how I can add the Witness subject into the tx? Is it as a result of I’m improperly including the scriptPubKey? I’m utilizing bitcoinjs 5.2.0
