Payment error "Transaction Failed"

Hi,

I’m working on a simple API, we are using this SDK but when we try on live with this script.

var StellarSdk = require('stellar-sdk');
StellarSdk.Network.usePublicNetwork();

var keypair = StellarSdk.Keypair.fromSecret('OUR SECRET');
var server = new StellarSdk.Server('https://horizon.stellar.org');

var sourceKeypair = StellarSdk.Keypair.random();
console.log(sourceKeypair.publicKey());
console.log(sourceKeypair.secret());

var secret = sourceKeypair.secret();
var public = sourceKeypair.publicKey();



server.loadAccount(keypair.publicKey())
  .then(function(source) {
    var transaction = new StellarSdk.TransactionBuilder(source)
      .addOperation(StellarSdk.Operation.payment({
        destination: public,
        amount: "1",
        asset: StellarSdk.Asset.native()
      }))
      .build();

    transaction.sign(keypair);

    return server.submitTransaction(transaction);
})
.then(function() {
  return server.loadAccount(public)
})
.catch(function(error) {
  console.error('Error!', error);
});

We create a new account and activate it with 1 lumen, the secret of the Payment have at least 1000 lumens, but when we make the transactions, it give this error:

Error! { [BadResponseError: Transaction submission failed. Server responded: 400 Bad Request]

        result_xdr: 'AAAAAAAAAGT/////AAAAAQAAAAAAAAAB////+wAAAAA=' } } }

Any advice?

Just noticed that this is a new keypair you’ve generated. Whenever you create a new keypair, you don’t necessarily create an account, which means you can’t send lumens to it yet. So for the first transaction to a newly created account (read, keyPair), instead of using the StellarSdk.Operation.payment operation, you should be using StellarSdk.Operation.createAccount.

Refer to the documentation of the create operation here: https://stellar.github.io/js-stellar-sdk/Operation.html#.createAccount

You’re welcome @bartekn

@ulisescarreonalvarez - I’ll try to answer your question from what I know.

As per the stellar network rules, an account is only said to be created when it is activated by depositing a fund (of at least 1 XLM). It might seem very confusing that to create an account you need to deposit funds, but to fund an account using the payment operation, you need to have an already activated account.

The payment operation isn’t designed to create an account on the network and fund it. I don’t know for sure, but this is my theory on why it could be so - The payment operation supports paying using a multitude of tokens, but an account is only said to be activated when it has 1 or more XLM tokens. So, what if someone tried to fund an uncreated account with some other token?

Hence, it may make sense to separate out the create account operation into a separate one, which can only be done using XLM token. Note that, the createAccount operation does not let you specify which token you want to fund it with. It only lets you input a destination and a startingBalance, which ensures that you are activating an account only using XLM tokens.

Hope that answers your question.
