psbt.addOutput not working adding outputs to PSBT.

[javiervargas]

Hi, I'm having an issue with my PSBT. Outputs are empty and when trying to sign on Legder I get "TransportStatusError: Ledger device: Invalid data received (0x6a80)."

Code:

`

const psbt = async function () {
const p2sh = createPayment('p2sh-p2ms(2 of 3)', xpubs, networks.testnet)
if (p2sh) {
    const redeemScript = p2sh.output;
    console.log("Redeem Script (hex):", redeemScript.toString('hex'));
} else {
    console.log("Could not generate P2SH transaction.");
}
const redeemScript = p2sh.output;
const {address} = bitcoin.payments.p2pkh({ pubkey: cosigner2Pubkey, network: bitcoin.networks.testnet })
const spendable = 10000;
const fees = spendable - 5000;
const totalToSend = spendable - fees;
const rawTx = '02000000000101880573fb870032e84f7a28fe0dffc57f4df9b8bf1951feea484c1efc861f1fb20000000000fdffffff02571f02000000000017a914ef7e3a4c09df771b92e49c38da2fd87f56b849f387a08601000000000017a91416c4f91e5419de87b7b1a439ee7344b2bb32126c870247304402207bb54e1cd710b282d3eeec18baa69a88ce2446167c804114e1c59b0f231bb86a02201acee5aef96b0fb2f2f86280d9b378a2b51a281ad7032b4e9167ccdafe5eb311012103deba8a8d6eb407da0558716c051b172b139934ea0ae471f4d696006c3a9627b334b43000';

I think you should submit this issue to Ledger!

[javiervargas]

Thanks for your answer @jasonandjay , I was thinking that I have some kind of error on my code due this old error. Ledger Error.

They said:

"The PSBT is incomplete, it doesn't contain basically anything other than the unsigned transaction. It is required to have all the information about the keys present in the transaction; in particular, the PSBT_GLOBAL_XPUB and the PSBT_IN_BIP32_DERIVATION are compulsory. You can find a few complete psbts in this folder, might help as a reference on how they should look like:"

Is there any issue related with way I'm adding output?

As Ledger said, you need to add the global xpub data.

Psbt should not be shown as JSON. It will just confuse you. The "outputs" are referring to the outputs field of the PSBT which is separate from the outputs of the transaction (which contains the value and address etc)...

psbt.updateGlobal({
  globalXpub: [
    {
      extendedPubkey, // 78 byte buffer (contents of xpub string decoded from base58check)
      masterFingerprint, // 4 byte buffer with masterFingerprint of the root private key
      path, // The path from the root private key to the xpub in extendedPubkey
    },
    { ... },
    { ... },
  ]
});

Thank you!, I've added global data and it's generated.
