RawTransaction send return mandatory-script-verify-flag-failed (Non-canonical DER signature)

See original GitHub issue

I’m using bitcoinjs-lib 3.3.2 and running 2 bitcoin-qt nodes 0.16 on -regtest . I have tried to sign transaction using bitcoinjs and run it in bitcoin-qt console with sendrawtransaction but receive “16: mandatory-script-verify-flag-failed (Non-canonical DER signature) (code -26)”

There is unspent transaction :

{
    "txid": "77d0b6383f93b528333b0f0bd68aab33a3d08cdd05c50e258a7b775d7bfd2527",
    "vout": 0,
    "address": "mhZ1A3Cyqg9XQnRpmYkqjdTzL8yTaBpFf2",
    "scriptPubKey": "21039a0c9cb7c374df809965e4cfeb109ee0e1c7f3a0ee4b4f0cea04eebf25a27ee7ac",
    "amount": 50.00000000,
    "confirmations": 101,
    "spendable": true,
    "solvable": true,
    "safe": true
  }

I use dumpprivkey to get fromWIF value and getnewaccount for the receiver account

The code I’m using:

var testnet = bitcoin.networks.testnet
var value = 50 * 10e7 - 10000;
var key = bitcoin.ECPair.fromWIF("cMrFVDpeP3wvmNRpHLerhtwPY1mwHN3BTYCV1vNtP4zSvvZm11KN", testnet);
var tx = new bitcoin.TransactionBuilder(testnet);
tx.addInput("77d0b6383f93b528333b0f0bd68aab33a3d08cdd05c50e258a7b775d7bfd2527", 0);
tx.addOutput("2N9W57WJHgh8Yiev6s5he1Qn99DkZyKSkYg", value);
tx.sign(0, key);
console.log(tx.build().toHex());

Ive tried with sigwit as well - same result:

var keyPair = bitcoin.ECPair.fromWIF('cPzku2sUaQacgoKNjmS3FZtVrFxB4JtHFiS8y44g9Dr4rMMNn9Di', testnet)
var pubKey = keyPair.getPublicKeyBuffer()
var pubKeyHash = bitcoin.crypto.hash160(pubKey)

var redeemScript = bitcoin.script.witnessPubKeyHash.output.encode(pubKeyHash)
var redeemScriptHash = bitcoin.crypto.hash160(redeemScript)

var scriptPubKey = bitcoin.script.scriptHash.output.encode(redeemScriptHash)
var address = bitcoin.address.fromOutputScript(scriptPubKey, testnet)

var txb = new bitcoin.TransactionBuilder(testnet)
txb.addInput("77d0b6383f93b528333b0f0bd68aab33a3d08cdd05c50e258a7b775d7bfd2527", 0);
txb.addOutput("2MxSE48F9ZgsTghEgNjzNEDZoZbQnR4fcfh", value);
txb.sign(0, keyPair, redeemScript, null, value)

console.log(txb.build().toHex());

Any advice would be greatly appriciated

@Vutov

64: no-witness-yet (code -26)

You might need a minimum block-height on regtest of 432 blocks for segwit… Try bitcoin-cli generate 432

@tangnv You are spending from P2SH with a P2PKH script.

You are making the transaction wrong.
