Cannot broadcast segwit transaction with two outputs

[liorwavebl]

I'm trying to broadcast segwit transactions with two outputs. When I'm trying to broadcast it, I'm receiving this error:
non-mandatory-script-verify-flag (Script failed an OP_EQUALVERIFY operation)

The signing is done via this code snippet:

redeemTx := wire.NewMsgTx(wire.TxVersion)
prevOut := wire.NewOutPoint(utxoHash, 0)
redeemTxIn := wire.NewTxIn(prevOut, nil, nil)
redeemTx.AddTxIn(redeemTxIn)
redeemTXOut0 := wire.NewTxOut(outputs[0].amount, destPkScript0)
redeemTx.AddTxOut(redeemTXOut0)
redeemTXOut1 := wire.NewTxOut(outputs[1].amount, destPkScript1)
redeemTx.AddTxOut(redeemTXOut1)

a := txscript.NewMultiPrevOutFetcher(map[wire.OutPoint]*wire.TxOut{
*utxo: {},
})
sigHashes := txscript.NewTxSigHashes(redeemTx, a)
totalAmount := outputs[0].amount + outputs[1].amount
sigScript, err := txscript.WitnessSignature(redeemTx, sigHashes, 0, totalAmount, destPkScript1, txscript.SigHashAll, wif.PrivKey, true)

You need to specify the previous output script for WitnessSignature and NewMultiPrevOutFetcher. The previous output script is the script (decoded address) of the input you are spending (not the one you are sending to).

But UTXO is NewOutPoint and does not contains amount field.

[guggero]

You need to look it up on-chain.

[liorwavebl]

by using getrawtransaction command?

[guggero]

Yes. Or gettxout.
