BdkException.unExpected(e: Unable to sign transaction) #80

Closed awaik closed 1 year ago

awaik commented 1 year ago

Description

  1. If I create a regular wallet I can create and sign a transaction.
  2. The bug appears when I create a multis wallet.
  3. In this case I can create a transaction.
  4. I can get transaction details.
  5. But when I tried to sign it I get a error BdkException.unExpected(e: Unable to sign transaction)

Code

  final txBuilder = TxBuilder();
  final Address addressModel = await Address.create(address: buyerAddress);
  final Script script = await addressModel.scriptPubKey();
  final txToBuyer = await txBuilder.feeRate(10.0).addRecipient(script, toBuyerSatoshies).finish(wallet);

  final sbt = await wallet.sign(txToBuyer.psbt);

I tried to sign a tx with a watch-only wallet. Maybe it is worth adding an error message about this.
