transactions – mandatory-script-verify-flag-failed (Signature must be zero for failed CHECK(MULTI)SIG operation)

I want to send raw transaction
But, I have a problem. I working with regtest node.
I generated p2pkh address with seed-phrase
mjnJj4TFyU4jYrTVUHMA632UmuUMssZHq4

Then generatetoaddress 101 block as always

My unspent

[
    {
        "txid": "6481bbba699177c735c3e336735674641459bbbe2aba85a1b8be233df8f36938",
        "vout": 0,
        "address": "mjnJj4TFyU4jYrTVUHMA632UmuUMssZHq4",
        "label": "",
        "scriptPubKey": "76a9142ec7cc30ef662cf7c757e3460995f2682871207688ac",
        "amount": 50,
        "confirmations": 101,
        "spendable": true,
        "solvable": false,
        "parent_descs": [
            "addr(mjnJj4TFyU4jYrTVUHMA632UmuUMssZHq4)#rwelz9me"
        ],
        "safe": true
    }
]

and after that i make transaction
just send little bit sats to another empty address

My steps:
1 . make empty transaction with 1 input and 2 outputs (1 for change)

CREATE TRANSACTION START
== Amount to send (sats): 100000000
== Fee (sats): 1000000
== Get UTXO id for pay: 6481bbba699177c735c3e336735674641459bbbe2aba85a1b8be233df8f36938
== Reversed UTXO id: 3869f3f83d23beb8a185ba2abebb59146474567336e3c335c7779169babb8164
== Full generated tx: {"version":1,"inputs":[{"txid":"3869f3f83d23beb8a185ba2abebb59146474567336e3c335c7779169babb8164","vout":0,"scriptSig":"76a9142ec7cc30ef662cf7c757e3460995f2682871207688ac","sequence":4294967295}],"outputs":[{"value":100000000,"scriptPubKey":"76a914796e2d78cff63c21f8ee823052b5362bc2cc2af388ac"},{"value":4899000000,"scriptPubKey":"76a914929b53a5d57f12e924b9c6d58524faec5c5cfee788ac"}],"locktime":0}
CREATE TRANSACTION END

2. then serialize it

SERIALIZATION END

3. Sign it

SIGNING END

What’s wrong ? In DER signature? Not in my data and algo?
Please help me. I wrote code for send raw transactions, research steps, but i guess i made a mistake somewhere

4. Final hex and command
