sendTransactionError: code:-3 message:"Script(ValidationFailure(-2)

[Wangmmx]

I have a problem when sending transaction, I followed the example of building a trading, only modified address and private key

https://github.com/nervosnetwork/ckb-sdk-js/blob/develop/packages/ckb-sdk-core/examples/sendTransaction.js

What is the clear mistake? thanks!

Adding my code here:

    const nodeUrl =******
    const core = new Core(nodeUrl)
    let secp256k1Dep = await core.loadSecp256k1Dep();

    let pubKey = '0x035a27b3564c6a08337ba07f8120551d5721e9ae888bcd60df705de7509d2bc73d';
    let address = CKBUtils.pubkeyToAddress(pubKey, {prefix: 'ckt'});

    let pubKeyHash = '0x' + CKBUtils.blake160(pubKey, 'hex');
    let codeHash = secp256k1Dep.codeHash;

    let lockScript = {
        hashType: "type",
        codeHash: codeHash,
        args: pubKeyHash
    }
    let lockHash = CKBUtils.scriptToHash(lockScript);
    let unspentCells = await core.loadCells({lockHash})

    let rawTransaction = await core.generateRawTransaction({
        fromAddress: 'ckt1qyqdjvjspzuj0vjg85duwl8s9a8x32u3ddksef5eqc',
        toAddress: 'ckt1qyqwkcma99gj3zlh2wwzzd2etawegg90lepssacpmh',
        capacity: 7000000000,
        fee: 100000,
        safeMode: true,
        cells: unspentCells,
        deps: core.config.secp256k1Dep,
    })

    rawTransaction.witnesses = rawTransaction.inputs.map(() => '0x')
    rawTransaction.witnesses[0] = {
        lock: '',
        inputType: '',
        outputType: ''
    }

    let privateKey = '0x7faf9bddf383c4ac07b32f7001905975c0b91761e9794590c4e5475583362bdc'
    const signedTx = core.signTransaction(privateKey)(rawTransaction);
    const realTxHash = await core.rpc.sendTransaction(signedTx);
    console.log('The real transaction hash is:', realTxHash)

I've run the example and it works

const Core = require('../lib').default

const bootstrap = async () => {
  const nodeUrl = 'http://localhost:8114'
  const core = new Core(nodeUrl)
  const secp256k1Dep = await core.loadSecp256k1Dep()
  const CKBUtils = core.utils

  const pubKey = '0x035a27b3564c6a08337ba07f8120551d5721e9ae888bcd60df705de7509d2bc73d'
  // const address = CKBUtils.pubkeyToAddress(pubKey, {
  //   prefix: 'ckt',
  // })

  const pubKeyHash = `0x${CKBUtils.blake160(pubKey, 'hex')}`
  const { codeHash } = secp256k1Dep

  const lockScript = {
    hashType: 'type',
    codeHash,
    args: pubKeyHash,
  }
  const lockHash = CKBUtils.scriptToHash(lockScript)
  const unspentCells = await core.loadCells({
    lockHash,
  })

  const rawTransaction = await core.generateRawTransaction({
    fromAddress: 'ckt1qyqdjvjspzuj0vjg85duwl8s9a8x32u3ddksef5eqc',
    toAddress: 'ckt1qyqwkcma99gj3zlh2wwzzd2etawegg90lepssacpmh',
    capacity: 7000000000,
    fee: 100000,
    safeMode: true,
    cells: unspentCells,
    deps: core.config.secp256k1Dep,
  })

  rawTransaction.witnesses = rawTransaction.inputs.map(() => '0x')
  rawTransaction.witnesses[0] = {
    lock: '',
    inputType: '',
    outputType: '',
  }

  const privateKey = '0x7faf9bddf383c4ac07b32f7001905975c0b91761e9794590c4e5475583362bdc'
  const signedTx = core.signTransaction(privateKey)(rawTransaction)
  const realTxHash = await core.rpc.sendTransaction(signedTx)
  console.log('The real transaction hash is:', realTxHash)
}

bootstrap()

Could you please post the versions of ckb-sdk-js and ckb, and the signed transaction generated by the sdk here? Thanks.

versions:
ckb-sdk-js:0.23.1
and I will ask ckb version later.

If the version of CKB is v0.24.*, I guess upgrading the SDK to v0.24.0 will fix this error.

The signature has changed in v0.24.
