My goal

Learn how to send a taproot output via bitcoin core's bitcoin-cli.

What I've tried

I imported a WIF utxo containing a v1 segwit utxo.

After: createrawtransaction then fundrawtransaction, I will attempt to sign with: signrawtransactionwithwallet but will get:

{
  "hex": "hex_from_fund_command",
  "complete": false,
  "errors": [
    {
      "txid": "from_v1_taproot_txid",
      "vout": n,
      "witness": [
      ],
      "scriptSig": "",
      "sequence": seq_num_not_sure_if_this_is_sensitive,
      "error": "Witness program was passed an empty witness"
    }
  ]
}

Note: witness and scriptSig are blank. I've tried not providing and not providing the prevtxs with no difference.

I'm unsure if I need to provide redeemScript or witnessScript, I'm unsure how to construct/find these.

         "txid": "hex",             (string, required) The transaction id
         "vout": n,                 (numeric, required) The output number
         "scriptPubKey": "hex",     (string, required) script key
         "redeemScript": "hex",     (string, optional) (required for P2SH) redeem script
         "witnessScript": "hex",    (string, optional) (required for P2WSH or P2SH-P2WSH) witness script
         "amount": amount,          (numeric or string, optional) (required for Segwit inputs) the amount spent

Question

• What are the methodical steps starting with an imported WIF/taproot utxo and ending with a signed tx?
