but I get a new error: non-mandatory-script-verify-flag (Invalid Schnorr signature).
I don't know what does the error mean.

It means your signature is invalid.

Without seeing the actual transaction, it's hard to actually provide specific help.

I called "decoderawtransaction" method and this is result. thank for your help.

Code:

I want to create a PSBT transaction. But get the error when to call sendrawtransaction method.

The error indicates that when sending your transaction to your node's mempool, it's rejected for referencing already spent output(s).
The TXIDs seem to be existing in the TestNet network.
Check your inputs' output_index (vout) if it's pointing to the correct UTXO.

You can also share the signed raw testnet transaction so others and I can help find the issue (and other issues) in the finalized transaction.

Thanks. The vout isn't correct. I have updated them and sent the transaction again. but I get a new error: non-mandatory-script-verify-flag (Invalid Schnorr signature).
I don't know what does the error mean.

I want to create a PSBT transaction. But get the error when to call sendrawtransaction method.

I used Golang package: github.com/btcsuite/btcd

This is my code:

PSBT inputs

Code:

inputs = append(inputs, &TxInput{
TxId: "02b074590fcac25129ff8f6a31375d9231e86f600f82c232d5d61fe2df5a8a96",
VOut: uint32(0),
Sequence: uint32(0),
Amount: 2774,
Address: "tb1pnq36mn7l8d3kvgejvnc5q63ls9umhaqscl623eqzge8mstj332xscmeu8h",
PublicKey: "02a33b6f980567e1b3bb5a4df3b086871694d0e03b70ee462a36686acda6b94b9d",
PrivateKey: "privatekey",
})

inputs = append(inputs, &TxInput{
TxId: "2e9f9af0bbed192bb860a172b2ab219c48da87996c7e80bf8470033b669f354e",
VOut: uint32(len(inputs)),
Sequence: uint32(len(inputs)),
Amount: 1990,
Address: config.Receiver,
PublicKey: "02e8e9d1d88eb86fb56b26e267bda715ba81ad91850448d8c2d5d8e64937ac8ef9",
PrivateKey: "privatekey",
})

PSBT outputs

Code:

func GetTxOutByUTXOs(amount int64) []*TxOutput {
var outputs []*TxOutput
outputs = append(outputs, &TxOutput{
Address: config.Owner,
Amount: amount - 500,
})
outputs = append(outputs, &TxOutput{
Address: config.Receiver,
Amount: 500 + 1990 - 300,
})

return outputs
}

Then I passed them to the function.

Code:

func GenerateSignedOwnerTx(ins []*TxInput, outs []*TxOutput, network *chaincfg.Params) (string, error) {
var inputs []*wire.OutPoint
var nSequences []uint32
prevOuts := make(map[wire.OutPoint]*wire.TxOut)
for _, in := range ins {
var prevOut *wire.OutPoint
txHash, err := chainhash.NewHashFromStr(in.TxId)
if err != nil {
panic(err)
}
prevOut = wire.NewOutPoint(txHash, in.VOut)
inputs = append(inputs, prevOut)

prevPkScript, err := AddrToPkScript(in.Address, network)
if err != nil {
panic(err)
}
witnessUtxo := wire.NewTxOut(in.Amount, prevPkScript)
prevOuts[*prevOut] = witnessUtxo

nSequences = append(nSequences, wire.MaxTxInSequenceNum)
}

var outputs []*wire.TxOut
for _, out := range outs {
pkScript, err := AddrToPkScript(out.Address, network)
if err != nil {
panic(err)
}
outputs = append(outputs, wire.NewTxOut(out.Amount, pkScript))
}

bp, err := psbt.New(inputs, outputs, int32(2), uint32(0), nSequences)
if err != nil {
panic(err)
}

updater, err := psbt.NewUpdater(bp)
if err != nil {
panic(err)
}

prevOutputFetcher := txscript.NewMultiPrevOutFetcher(prevOuts)

for i, in := range ins {

if err = signInput(updater, i, in, prevOutputFetcher, txscript.SigHashAll, network); err != nil {
panic(err)
}

if err = psbt.Finalize(bp, i); err != nil {
panic(err)
}
}

fmt.Println("signed bp base64 encode:")
fmt.Println(bp.B64Encode())
if err = psbt.MaybeFinalizeAll(bp); err != nil {
return "", err
}

buyerSignedTx, err := psbt.Extract(bp)
if err != nil {
return "", err
}

var buf bytes.Buffer
if err := buyerSignedTx.Serialize(&buf); err != nil {
return "", err
}

return hex.EncodeToString(buf.Bytes()), nil}

This is sign function.

Code:

func signInput(updater *psbt.Updater, i int, in *TxInput, prevOutFetcher *txscript.MultiPrevOutFetcher, hashType txscript.SigHashType, network *chaincfg.Params) error {
wif, err := btcutil.DecodeWIF(i[Suspicious link removed]ivateKey)
if err != nil && i != 1 {
panic(err)
}
privKey := wif.PrivKey

prevPkScript, err := AddrToPkScript(in.Address, network)
if err != nil {
panic(err)
}
if txscript.IsPayToPubKeyHash(prevPkScript) {
prevTx := wire.NewMsgTx(2)
txBytes, err := hex.DecodeString(in.NonWitnessUtxo)
if err != nil {
panic(err)
}
if err = prevTx.Deserialize(bytes.NewReader(txBytes)); err != nil {
panic(err)
}
if err = updater.AddInNonWitnessUtxo(prevTx, i); err != nil {
panic(err)
}
} else {
witnessUtxo := wire.NewTxOut(in.Amount, prevPkScript)
if err = updater.AddInWitnessUtxo(witnessUtxo, i); err != nil {
panic(err)
}
}

if err = updater.AddInSighashType(hashType, i); err != nil {
panic(err)
}

if txscript.IsPayToTaproot(prevPkScript) {
internalPubKey := schnorr.SerializePubKey(privKey.PubKey())
updater.Upsbt.Inputs[i].TaprootInternalKey = internalPubKey

sigHashes := txscript.NewTxSigHashes(updater.Upsbt.UnsignedTx, prevOutFetcher)
if hashType == txscript.SigHashAll {
hashType = txscript.SigHashDefault
}
witness, err := txscript.TaprootWitnessSignature(updater.Upsbt.UnsignedTx, sigHashes,
i, in.Amount, prevPkScript, hashType, privKey)
if err != nil {
panic(err)
}

updater.Upsbt.Inputs[i].TaprootKeySpendSig = witness[0]
} else if txscript.IsPayToPubKeyHash(prevPkScript) {
signature, err := txscript.RawTxInSignature(updater.Upsbt.UnsignedTx, i, prevPkScript, hashType, privKey)
if err != nil {
panic(err)
}

if _, err := updater.Sign(i, signature, privKey.PubKey().SerializeCompressed(), nil, nil); err != nil {
panic(err)
}
} else {
pubKeyBytes := privKey.PubKey().SerializeCompressed()
sigHashes := txscript.NewTxSigHashes(updater.Upsbt.UnsignedTx, prevOutFetcher)

script, err := PayToPubKeyHashScript(btcutil.Hash160(pubKeyBytes))
if err != nil {
panic(err)
}
signature, err := txscript.RawTxInWitnessSignature(updater.Upsbt.UnsignedTx, sigHashes, i, in.Amount, script, hashType, privKey)
if err != nil {
panic(err)
}

if txscript.IsPayToScriptHash(prevPkScript) {
redeemScript, err := PayToWitnessPubKeyHashScript(btcutil.Hash160(pubKeyBytes))
if err != nil {
panic(err)
}
err = updater.AddInRedeemScript(redeemScript, i)
if err != nil {
panic(err)
}
}

if _, err := updater.Sign(i, signature, pubKeyBytes, nil, nil); err != nil {
panic(err)
}
}
return nil}
