UniSat Wallet Taproot address and Dummy UTXO - Missing witness utxo

[GregorWedlich]

When I sign the dummy UTXO, I get this error with the taproot address format, but it works fine with SegWit:

Error:
Cannot finalize input #0. Missing withness utxo.

The problem is related to this issue:

#2

Works but with offet :0:1000:

witnessUtxo: tx.outs[utxo.vout],

Not work:

nonWitnessUtxo: tx.toBuffer(),

Error:
Cannot finalize input #0. Missing withness utxo.
