Paypal: PHP SDK error Incoming JSON request does not map to API request

I am using the PHP Paypal SDK: https://github.com/paypal/PayPal-PHP-SDK

The PayPal REST API being sent via the PHP SDK return and the request for incoming JSON requests are not mapped to the API request

Based on an existing transaction identifier, you need to get a payment identifier

I tried below code

require __DIR__ . '/bootstrap.php';

use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\CreditCard;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\FundingInstrument;
use PayPal\Api\Transaction;
// Extra Code
use PayPal\Api\PaymentDetail;

$payer = new Payer();
$payer->setPaymentMethod('paypal');

$transaction = new PaymentDetail(
        '{
          "method" : "CASH",
          "date" : "2014-07-06 03:30:00 PST",
          "note" : "Cash received."
        }'
);

$transaction->setTransactionId("3NT32794KF4824703");

$payment = new Payment();
$payment->setIntent("sale")
        ->setPayer($payer)
        ->setTransactions(array($transaction));

// For Sample Purposes Only.
$request = clone $payment;

try {
    $payment->create($apiContext);
} catch (\PayPal\Exception\PayPalConnectionException $ex) {
    echo $ex->getData();
}

echo "<pre>";
print_r($payment);
exit;

When I run the code above, it gives below error view

                                )

                        )

                )

        )

)

$payment = new Payment();
    $payment->setIntent("sale")
    ->setPayer($payer)
    ->setRedirectUrls($redirectUrls)
    ->setTransactions(array($transaction));    
$payment->create($apiContext);

• "URL- apporval", URL- , .

• paypal , URL "$ redirectUrls".

• " " " ", .

  $execution = new PaymentExecution();
  $execution->setPayerId($da['PayerID']);
  $apiContext=$this->apicontext();
  $res = $payment->execute($execution, $apiContext);
