bitcoin core – PSBT Transaction RPC Error: bad-txns-inputs-missingorspent

I need to create a PSBT transaction.
However get the error when to name sendrawtransaction technique.

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

That is my code:

PSBT inputs

PSBT outputs

Then I handed them to the operate.

func GenerateSignedOwnerTx(ins []*TxInput, outs []*TxOutput, community *chaincfg.Params) (string, error) {
var inputs []*wire.OutPoint
var nSequences []uint32
prevOuts := make(map[wire.OutPoint]*wire.TxOut)
for _, in := vary 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.Handle, community)
    if err != nil {
        panic(err)
    }
    witnessUtxo := wire.NewTxOut(in.Quantity, prevPkScript)
    prevOuts[*prevOut] = witnessUtxo

    nSequences = append(nSequences, wire.MaxTxInSequenceNum)
}

var outputs []*wire.TxOut
for _, out := vary outs {
    pkScript, err := AddrToPkScript(out.Handle, community)
    if err != nil {
        panic(err)
    }
    outputs = append(outputs, wire.NewTxOut(out.Quantity, 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 := vary ins {

    if err = signInput(updater, i, in, prevOutputFetcher, txscript.SigHashAll, community); 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}

That is signal operate.
