Transaction submit error MissingVKeyWitnessesUTXOW

Question

I am @emurgo/cardano-serialization-lib-nodejs to submit transaction in cardano.

I am getting following error.

Transaction 5c98317bc6caf027b91e807ed1cdd78571b8f9a791202b5feff5b32fa5f71f1f rejected,
message: "transaction submit error ShelleyTxValidationError ShelleyBasedEraBabbage

\"7afb7e3bfc4a25c9b5387657e8f71ae0c2d5f3b26142b51592785972\"])))))])"

I checked https://forum.cardano.org/t/blockfrostservererror-transaction-submit-error-shelleytxvalidationerror-shelleybasederababbage-applytxerror-utxowfailure-fromalonzoutxowfail-wrappedshelleyerafailure-missingvkeywitnessesutxow-withashes-fromlist-keyhash-b5cfe7a19bd626bd0d26657e/114662 and I am using utxoKey as signKey, but I am still getting above error.

How can I fix it?

Following is my code snippet to get signKey and address.

const accountKey = bipPrvKey
    .derive(harden(44)) // purpose
    .derive(harden(1815)) // coin type
    .derive(harden(0)); // account #

  const utxoKey = accountKey
    .derive(0) // external
    .derive(0);

  const utxoPubKey = utxoKey.to_public();

  const byronAddr = CardanoWasm.ByronAddress.icarus_from_key(
    utxoPubKey,
    CardanoWasm.NetworkInfo.mainnet().protocol_magic()
  );

  const address = byronAddr.to_base58();

  return { signKey: utxoKey.to_raw_key(), address: address };

I suggest you use this code instead (Shelley address, not Byron):

    const accountKey = rootKey
      .derive(harden(1852)) // purpose
      .derive(harden(1815)) // coin type
      .derive(harden(0)); // account #0
    
    const utxoPubKey = accountKey
      .derive(0) // external
      .derive(0)
      .to_public();
    
    const stakeKey = accountKey
      .derive(2) // chimeric
      .derive(0)
      .to_public();

const baseAddr = CardanoWasm.BaseAddress.new(
  CardanoWasm.NetworkInfo.mainnet().network_id(),
  CardanoWasm.StakeCredential.from_keyhash(utxoPubKey.to_raw_key().hash()),
  CardanoWasm.StakeCredential.from_keyhash(stakeKey.to_raw_key().hash()),
);

const address = baseAddress.to_address();
