Error sending Monero transactions to my daemon [tx used wrong inputs]

Question

After several checks made with the help of the community here on Stack-Exchange, I was able to move forward with my problem.

Now I have reached the point that the transactions are not sent even though the wallet is active and connected correctly.

Checking the logs of my Monero full-node on Testnet, when I try to send the transaction, I get this error log:

2023-08-19 16:46:23.292 E Key image already spent in blockchain: b561176c54524cde8f5311d8304f45a2fae1c48395a0502cc30e48a86df6d2c7
2023-08-19 16:46:23.293 I tx used wrong inputs, rejected
2023-08-19 16:46:23.293 E Transaction verification failed: <1291ff117cab830744fc7f7e401046656c623db1e04a718fd5b6dbbeced27d64>
2023-08-19 16:46:23.294 W [on_send_raw_tx]: tx verification failed: double spend, invalid input

Apparently the transaction uses wrong inputs, but I can't figure out why.

Below is the complete js code using the monero-javascript library:

async function sendTransaction(toAddress, amount) {
    const daemon = await monerojs.connectToDaemonRpc("http://localhost:28081");    
    let wallet = await MoneroWalletFull.openWallet({
        path: `<mypath>`,
        password: password,
        networkType: MoneroNetworkType.TESTNET,
        serverUri: "http://127.0.0.1:28081"
      });
  daemonHeight = await daemon.getHeight();
  let sync = await syncWallet(wallet, daemonHeight)
  console.log(&quot;Wallet opened&quot;+ sync);

  walletHeight = await wallet.getHeight();

  console.error(&quot;Wallet height:&quot;, walletHeight);
  console.error(&quot;Daemon height:&quot;, daemonHeight);
  let isSynced = walletHeight === daemonHeight;
  if (isSynced) {
    console.log(&quot;Wallet is synchronized with the daemon&quot;);
  } else {
    console.error(&quot;Wallet is not synchronized with the daemon&quot;);
    console.error(&quot;Wallet height:&quot;, walletHeight);
    console.error(&quot;Daemon height:&quot;, daemonHeight);
    return;
  }

const balance = await getBalance(wallet);

if (balance &lt; amount) {
  throw new Error('Insufficient balance');
}

let unlockedBalance = await wallet.getUnlockedBalance(0, 0)

let amountInAtomic = ATOMICUNIT_PER_XMR * amount

if(unlockedBalance&lt;=amountInAtomic){
    throw new Error(&quot;Error no unlocked balance&quot;)
}
// TX SENDING AND CREATION
const tx = await wallet.createTx({
  accountIndex: 0,
  address: toAddress,
  amount: amountInAtomic.toString(),
  relay:true
});
let hash = tx.state.hash
return hash

}
async function syncWallet(wallet, height) {
  try {
    const syncResult = await wallet.sync(height);
    console.log('Sync progress:', syncResult);
    await wallet.save()
    if (!(await wallet.isSynced())) {
      throw new Error("Errore durante la sincronizzazione!")
    }
    else return true
  } catch (error) {
    throw new Error("Error during sync of the wallet: " + error.message);
  }
}
async function getBalance(wallet) {
      const balance = parseFloat((await wallet.getBalance(0)).toString()) / ATOMICUNIT_PER_XMR
      const unlockedBalance = await getUnlockedBalance(wallet)
      let balances= {balance,unlockedBalance}
      return balances
    }
async function getUnlockedBalance(wallet) {
      const balance = parseFloat((await wallet.getUnlockedBalance(0, 0)).toString()) / ATOMICUNIT_PER_XMR
      return balance
    }

Could you help me understand how to solve this error by providing me code examples or useful links to solve this problem?
