XRP send function does not work. The latest ledger sequence 36750915 is greater than the transaction's LastLedgerSequence

Question

This is my xrpl function. It comes from the xrpl tutorial and should work. But it returns tefBAD_AUTH error.

I am writing the xrpl dapps and it is kind of web3.

const xrpl = require("xrpl");

const poolSecret = "sEd**********************";
const poolWallet = xrpl.Wallet.fromSeed(poolSecret)

async function main(addr) {
  console.log("Connecting to Testnet...")
  const client = new xrpl.Client('wss://s.altnet.rippletest.net:51233')
  await client.connect()

  // Prepare transaction -------------------------------------------------------
  const prepared = await client.autofill({
    "TransactionType": "Payment",
    "Account": addr,
    "Amount": xrpl.xrpToDrops("1"),
    "Destination": poolWallet.address
  })
  const max_ledger = prepared.LastLedgerSequence
  console.log("Prepared transaction instructions:", prepared)
  console.log("Transaction cost:", xrpl.dropsToXrp(prepared.Fee), "XRP")
  console.log("Transaction expires after ledger:", max_ledger)

  // Sign prepared instructions ------------------------------------------------
  const signed = poolWallet.sign(prepared)
  console.log("Identifying hash:", signed.hash)
  console.log("Signed blob:", signed.tx_blob)

  // Submit signed blob --------------------------------------------------------
  try {
    const tx = await client.submitAndWait(signed.tx_blob)

    // Wait for validation -------------------------------------------------------
    // submitAndWait() handles this automatically, but it can take 4-7s.

    // Check transaction results -------------------------------------------------
    console.log("Transaction result:", tx.result.meta.TransactionResult)
    console.log("Balance changes:", JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2))

    // End of main()
    client.disconnect()
  } catch (e) {
    console.log(e)
  }
}

main("rf*******************************");

But it returns this error. This is the full logs.

The address that I use works fine in the wallet.

I am using ubuntu 20.04 and I tried this with node v14 & v16.

Two things to try:

1. From the "bad auth" message Change the client you are trying to connect to, try "wss://testnet.xrpl-labs.com/" which explicitly has CORS support (https://xrpl.org/public-servers.html)

2. From the "latest ledger sequence..." message Short answer: try changing, (or explicitly setting) your Flags value to 2147483648.

Long answer: I had the same error for an "NFTokenCreateOffer" transaction type. It corrected for me when I set the "Flags" property of my transaction to a correct value.

From your output, it looks like your Flags is set to 0 which I don't think matches any true flag for the payment transaction type.

I have a my own system that I have coded that utilizes the "payment" transaction, in which I set Flags to "2147483648" (tfFullyCanonicalSig - https://xrpl.org/transaction-common-fields.html#flags-field), which I know says is deprecated, but it works for me.

My payment transaction looks like this prior to autofill being called:

const transaction = {
    TransactionType: 'Payment',
    Account: walletDto.address,
    Amount: amount,
    Destination: sendDetails.sendToAddress,
    Flags: 2147483648, 
  };

I hope this helps

Answer 2

I received this error where I tried to move funds from Account -> Destination but I wasn't the owner of "Account": addr, In the following function you wrote:

const prepared = await client.autofill({
    "TransactionType": "Payment",
    "Account": addr,                   <= // Do you own this wallet ?
    "Amount": xrpl.xrpToDrops("1"),
    "Destination": poolWallet.address  <= // I see above that you own this one
  })

If for testing purposes you're trying to just work out this code, try to switch between addr and poolWallet.address
