Using payment operation with other asset, informing the amout

[RASTecnoTI]

Hi

I tested the code and worked very well.

I would like to know if is possibile create one payment using um asset instead XLM (in my case called TREEP) and inform the amout to transfer?
I tested using 04-submit-transaction.php

Like this:

Thank you!

I guess that is this block

// Build the payment transaction
$transaction = \ZuluCrypto\StellarSdk\Server::publicNet()
->buildTransaction($sourceKeypair->getPublicKey())
->addOperation(
PaymentOp::newNativePayment($destinationAccountId, 1)
)
;

Good afternoon, I have the same problem, how should I do to inform a payment using TREEP, I am trying as I exercise below but I return error 504
$asset = Asset::newCustomAsset('TREEP', "GAVBWV24PZ6POVQGQO5UEWGO3TO7ERYXRFFI6V5VH3BMTPDZOHVOFA3G");

            $txEnvelope = $server->buildTransaction( $origem_keypar )
                                 ->setTextMemo($data['memorando'])
                                 ->addCustomAssetPaymentOp($asset,  $valor, $destino_keypar )
                                 ->getTransactionEnvelope();

$txEnvelope->sign($origem_keypar);

        $b64Tx = base64_encode($txEnvelope->toXdr());
        
        $return = $server->submitB64Transaction($b64Tx);
