I have created a simple function, which is basically almost identical to the one in the stellar documentation "Sending and receiving custom assets" found here
I constantly get error 504 timeouts ... it's basically timing out every single time I try it.
Note - the secret keys referred to in the function declaration relate to funded accounts on the stellar testnet.
My function differs from the stellar one as follows: - it has "fee:200" and "fee:500" in the .TransactionBuilder calls [as now recommended by stellar I believe) (I experimented with values here, no difference found, still get 504 timeout).
function TryStellarEntireScenario ( SK_Issuer , SK_Distributor ,SK_userSender ,SK_userReceiver ) {
// the SK's are the Secret keys
var server = new StellarSdk.Server('https://horizon-testnet.stellar.org');
StellarSdk.Network.useTestNetwork();
// The other set-ups from the server are done further up this source code file
// Keys for accounts to issue and receive the new asset
var issuingKeys = StellarSdk.Keypair
.fromSecret(SK_Issuer);
var receivingKeys = StellarSdk.Keypair
.fromSecret(SK_Distributor);
// Create an object to represent the new asset
var astroDollar = new StellarSdk.Asset('AstroDollar', issuingKeys.publicKey());
// First, the receiving account must trust the asset
server.loadAccount(receivingKeys.publicKey())
.then(function(receiver) {
var transaction = new StellarSdk.TransactionBuilder(receiver, {fee:200})
// The `changeTrust` operation creates (or alters) a trustline
// The `limit` parameter below is optional
.addOperation(StellarSdk.Operation.changeTrust({
asset: astroDollar,
limit: '1000'
}))
// setTimeout is required for a transaction
.setTimeout(100)
.build();
transaction.sign(receivingKeys);
return server.submitTransaction(transaction);
})
// Second, the issuing account actually sends a payment using the asset
.then(function() {
return server.loadAccount(issuingKeys.publicKey())
})
.then(function(issuer) {
var transaction = new StellarSdk.TransactionBuilder(issuer, {fee:500})
.addOperation(StellarSdk.Operation.payment({
destination: receivingKeys.publicKey(),
asset: astroDollar,
amount: '10'
}))
// setTimeout is required for a transaction
.setTimeout(100)
.build();
transaction.sign(issuingKeys);
return server.submitTransaction(transaction);
})
.catch(function(error) {
console.error('Error!', error);
});
}
Here is the error log:
