Possibly unhandled Error: No free outputs to spend

[anjalialance]

Hello,

I am new to bitcoin transactions. I am using bitcoinjs-lib and blockexplorer for the transaction. The thing that is happening with me is that if I am entering new address that is generated by bip32 and bip39

The address and private key are-

sender address - motCmpWMeMC6BTRUtryxMATUBCvGorAjcs private key - L1Eoyo3BN41AAxZE1wrJrHYNoxHZhNrtKtgTHVG1axiXJcs6TCkj receiver address - myQdZsy9wRd4A7deRBm88RZX9rv19NDGyB

then it is giving me error. Also, if i am entering the address which I have previously used in transaction procedures. It is generating same transaction ids again and again.

The address that i am using for this is -

sender address - mkX9cVJDWjPxxfwNvYg58fbR2vHRfuU6XJ private key - KwV364bGF83ie4wJSwzV4hccbLeyMnFSVwyPvdMEnU8cr6Nyu25U receiver address - mthGgBTX1kxibjXwXxy5jraBNtTsajpqSx

Thank you in advance.!

1. Format, please.
2. You're mixing up addresses.
3. Where exactly is your problem? bitcoinjs-lib doesn't use promises, so it looks like your problem is not with bitcoinjs-lib. but you just pasted a huge blob of messy un-formatted code. No clue.

Please be more precise in your question.

Thanks.

Hi,

Thanks for the reply I am providing you the main code for transaction-

const bitcoin = require('bitcoinjs-lib')
const blockexplorer = require('blockchain.info/blockexplorer').usingNetwork(3)

const wif = 'cRboSi32o7hRLQ2VQMfSDc3SSBayMpxaPvpvPuiX65NXZMwLw1zT'
const key = bitcoin.ECPair.fromWIF(wif, bitcoin.networks.testnet)
const wallet = bitcoin.payments.p2pkh({
  pubkey: key.publicKey,
  network: bitcoin.networks.testnet
})
// wallet.address === motCmpWMeMC6BTRUtryxMATUBCvGorAjcs

blockexplorer.getUnspentOutputs(wallet.address).then(result => {
  wallet.utxos = result.unspent_outputs
  const sending = 10000
  console.log(sending)
  const txb = new bitcoin.TransactionBuilder(bitcoin.networks.testnet)
  txb.setVersion(2)
  var input = 0
  for (let utx of wallet.utxos) {
    txb.addInput(utx.tx_hash_big_endian, utx.tx_output_n)
    input += utx.value
    if (input >= sending) break
  }
  const change1 = 17466476 - sending
  const fee = 1000
  const change = input - (sending + fee)
  txb.addOutput('myQdZsy9wRd4A7deRBm88RZX9rv19NDGyB', sending)
  if (change) txb.addOutput('motCmpWMeMC6BTRUtryxMATUBCvGorAjcs', change)
  txb.sign(0, key)
  const raw = txb.build().toHex()
  console.log(raw)
})

This is the code of transaction

and the code for wallet creation is-

var keyPair = bitcoin.ECPair.makeRandom();
var testnet = bitcoin.networks.testnet;
var {address} = bitcoin.payments.p2pkh({pubkey : keyPair.publicKey, network: testnet});
var privateKey=keyPair.toWIF();

blockchain info API is broken.

Please ask them to fix it. (This issue looks related: https://github.com/blockchain/api-v1-client-node/issues/90 )

This is irrelevant to our library, so I will close it. Thanks.

Okay Thanks!
