bitcoin cli – Create and spend P2WSH that locks cash with OP_CHECKLOCKTIMEVERIFY

I am making an attempt to create a P2SWH tackle with a script that locks the cash for a while. After which I wish to spend these cash from that tackle.

I’ve learn quite a bit, a number of the most related:

These are the steps I’ve taken. The place am I going fallacious?

1. Create an tackle to be locked

bitcoin-cli -regtest -getnewaddress
bcrt1q45rq22tegkfu4sl9tfhty6svvkyaj6q4wu43fs

2. Get the pubkey

bitcoin-cli -regtest getaddressinfo bcrt1q45rq22tegkfu4sl9tfhty6svvkyaj6q4wu43fs
{
  "tackle": "bcrt1q45rq22tegkfu4sl9tfhty6svvkyaj6q4wu43fs",
  "scriptPubKey": "0014ad060529794593cac3e55a6eb26a0c6589d96815",
  "ismine": true,
  "solvable": true,
  "desc": "wpkh([10304ad5/84'/1'/0'/0/0]0340469e0bd5cca35c04bcee20e203f8fe601b69d73793b493fe92900e620b67d8)#52elxezw",
  "parent_desc": "wpkh([10304ad5/84'/1'/0']tpubDDr5yrdp9CqDy4qv2Waa1Z5aeQUzQh4Rxs84XyT8vHXTNKEaR6rDhTY56sSYC4vBdbKj1fHbwEPuimcu1yY3RSN8u1RvSREdyAUEDmfWzFv/0/*)#82xg44pv",

  "hdmasterfingerprint": "10304ad5",
  "labels": [
    ""
  ]
}

3. Convert pubkey into pubkeyhash

echo -n 0340469e0bd5cca35c04bcee20e203f8fe601b69d73793b493fe92900e620b67d8 | xxd -r -p | openssl dgst -sha256 -binary | openssl dgst -rmd160
ad060529794593cac3e55a6eb26a0c6589d96815

4. Get little-endian hex of timestamp for 1 March 2023 (1677628800)

printf '%xn' 1677628800 | fold -w2 | tac | tr -d "n"
8095fe63

5. Create script utilizing btcc from btcdeb

btcc 8095fe63 OP_CHECKLOCKTIMEVERIFY OP_DROP OP_DUP OP_HASH160 ad060529794593cac3e55a6eb26a0c6589d96815 OP_EQUALVERIFY OP_CHECKSIG
048095fe63b17576a914ad060529794593cac3e55a6eb26a0c6589d9681588ac

6. Get ScriptHash

echo -n 048095fe63b17576a914ad060529794593cac3e55a6eb26a0c6589d9681588ac | xxd -r -p | openssl dgst -sha256
5ef75077ffb6e6d533f4245d1ece3c6034ea315db818906dfb49a643e27068fb

7. Decode script to test and get P2WSH (or might compute)

bitcoin-cli -regtest decodescript 048095fe63b17576a914ad060529794593cac3e55a6eb26a0c6589d9681588ac
{
  "asm": "1677628800 OP_CHECKLOCKTIMEVERIFY OP_DROP OP_DUP OP_HASH160 ad060529794593cac3e55a6eb26a0c6589d96815 OP_EQUALVERIFY OP_CHECKSIG",
  "desc": "uncooked(048095fe63b17576a914ad060529794593cac3e55a6eb26a0c6589d9681588ac)#snjtcwv8",
  "kind": "nonstandard",
  "p2sh": "2N6zwcmxWbwkcVRwY275T8UXJ9mR9AtFaQo",
  "segwit": {

    "hex": "00205ef75077ffb6e6d533f4245d1ece3c6034ea315db818906dfb49a643e27068fb",

    "p2sh-segwit": "2N5EceqhW9HtQxRnL8qRCscz8Udv9P3bvwT"
  }
}

8. Ship some cash to handle (after which generate some blocks to substantiate txn)

bitcoin-cli -regtest -named sendtoaddress tackle="bcrt1qtmm4qallkmnd2vl5y3w3an3uvq6w5v2ahqvfqm0mfxny8cnsdrashv8fsr" quantity="1.0" fee_rate=1.0
3259e33b721664a5aadae575a6870d1c26750cad789925f7df0282ac1a76f75c

Above txn decoded

  ]
}

9. Create a brand new tackle to ship to and outline some variables, then create uncooked txn

LOCKTIME=247
OUT_ADDR=bcrt1qmydu04snguq9lrtg9rmenu4dvx0zzlefdtpe8p
OUT_AMNT="0.998"
IN_TXID=3259e33b721664a5aadae575a6870d1c26750cad789925f7df0282ac1a76f75c
IN_VOUT=1

bitcoin-cli -regtest -named createrawtransaction inputs="[{"txid":""$IN_TXID'", "vout":'$IN_VOUT'}]' outputs="[{""$OUT_ADDR'":'$OUT_AMNT'}]' locktime=$LOCKTIME replaceable=true
02000000015cf7761aac8202dff7259978ad0c75261c0d87a675e5daaaa56416723be359320100000000fdffffff01c0d3f20500000000160014d91bc7d61347005f8d6828f799f2ad619e217f297e022500

10. Create scriptpubky: OP_HASH160 hash160(redeemScript) OP_EQUAL
    redeemScript is 0200 + scripthash (I am not too certain about this step…)

echo -n 00205ef75077ffb6e6d533f4245d1ece3c6034ea315db818906dfb49a643e27068fb | xxd -r -p | openssl dgst -sha256 -binary | openssl dgst -rmd160
838403567aa049ada65f944d0a2a320d7b93e7ee
# mix remainder of script hex
A914838403567aa049ada65f944d0a2a320d7b93e7ee87

11. Extra variables and try to signal uncooked txn

TX_DATA=02000000015cf7761aac8202dff7259978ad0c75261c0d87a675e5daaaa56416723be359320100000000fdffffff01c0d3f20500000000160014d91bc7d61347005f8d6828f799f2ad619e217f29f7000000

SCRIPTPUBKEY=A914838403567aa049ada65f944d0a2a320d7b93e7ee87

bitcoin-cli -regtest -named signrawtransactionwithwallet hexstring=$TX_DATA prevtxs="[{"txid":""$IN_TXID'","vout":'$IN_VOUT',"redeemScript":"'$REDEEMSCRIPT'","scriptPubKey":"'$SCRIPTPUBKEY'","witnessScript":"'$WITNESSCRIPT'","amount":"'$OUT_AMNT'"}]'

error code: -22
error message:
Earlier output scriptPubKey mismatch:

vs:
OP_HASH160 838403567aa049ada65f944d0a2a320d7b93e7ee OP_EQUAL

Primarily based on that error, it appears to be anticipating the redeemscript, so I give {that a} try to get a distinct error:

bitcoin-cli -regtest -named signrawtransactionwithwallet hexstring=$TX_DATA prevtxs="[{"txid":""$IN_TXID'","vout":'$IN_VOUT',"redeemScript":"'$REDEEMSCRIPT'","scriptPubKey":"'$REDEEMSCRIPT'","witnessScript":"'$WITNESSCRIPT'","amount":"'$OUT_AMNT'"}]'

      "sequence": 4294967293,
      "error": "Witness program was handed an empty witness"
    }
  ]
}

Wanting on the decoded hex of this incomplete txn, I see there is no such thing as a witness knowledge. Am I alleged to be supplying that? I am in all probability getting one thing fallacious alongside the best way, however unsure what.
