The following code creates an account, except for the part where I try to add a trust line to an asset. It returns a code 400. What am I writing incorrectly regarding the add trust operation?
const express = require('express')
const app = express()
const StellarSdk = require('stellar-sdk');
StellarSdk.Network.useTestNetwork();
var server = new StellarSdk.Server('https://horizon-testnet.stellar.org');
const source = StellarSdk.Keypair.fromSecret('SK0x0...')
const counterAsset = new StellarSdk.Asset('XAG', 'PK0x0...')
app.get("/wallet", (req, res) => {
const keyPair = StellarSdk.Keypair.random();
console.log(keyPair.publicKey())
console.log(keyPair.secret())
server.accounts()
.accountId(source.publicKey())
.call()
.then(({ sequence }) => {
const account = new StellarSdk.Account(source.publicKey(), sequence)
const builder = new StellarSdk.TransactionBuilder(account, {
fee: 300
})
builder.addOperation(StellarSdk.Operation.createAccount({
destination: keyPair.publicKey(),
startingBalance: '3.4'
}))
***THIS CHANGE TRUST OPERATION CAUSES REQUEST TO FAIL.
builder.addOperation(StellarSdk.Operation.changeTrust({
asset: counterAsset,
amount: '1000000000000',
source: keyPair.publicKey()
}))
const transaction = builder.build()
transaction.sign(source)
return server.submitTransaction(transaction)
})
.then(results => {
console.log('Transaction', results._links.transaction.href)
console.log('success')
res.send({
publicKey: keyPair.publicKey(),
secretKey: keyPair.secret(),
})
})
.catch(err => {
console.log('error', err);
})
})
app.listen(3003, () => {
console.log('Server is up and running on port 3003')
})
I am getting a bad request error as follows:

And lastly, how can I handle the error, so the request isn't sent over and over? Regards
