PayPalConnectionExceptionをキャッチする方法は？

Question

私はPayPal-PHP-SDKのPayPalConnectionExceptionをキャッチできないようです。私はPayPalの-PHP-SDK GithubのWikiページからの例を使用し、私のコードは次のようになります。それはまだキャッチされない例外エラーを出力し、いくつかの理由で

<?php 

require 'start.php'; 

use PayPal\Api\Payment; 
use PayPal\Api\PaymentExecution; 

$serverName = "http://" . $_SERVER['SERVER_NAME']; 


if(!isset($_GET['success'], $_GET['paymentId'], $_GET['PayerID'])){ 
    header("Location: $serverName/cancel"); 
    exit(); 
} 

if((bool)$_GET['success'] === false){ 
    header("Location: $serverName/cancel"); 
    exit(); 
} 

$paymentId = $_GET['paymentId']; 
$payerID = $_GET['PayerID']; 

$payment = Payment::get($paymentId, $paypal); 

$execute = new PaymentExecution(); 
$execute->setPayerId($payerID); 

try{ 
    $payment->execute($execute, $paypal); 
    header("Location: $serverName/payments/success"); 
    //exit(); 
} catch (PayPal\Exception\PayPalConnectionException $ex) { 
    echo $ex->getCode(); // Prints the Error Code 
    echo $ex->getData(); // Prints the detailed error message 
    die($ex); 
} catch(Execption $e){ 
    $data = json_decode($e->getData()); 
    header("Location: $serverName/payments/failed.php?err=" . $data->message); 
    //echo $data->message; 
    die($e); 
} 

。ここに私のログがあります：

try{ 
    $payment->execute($execute, $paypal); 
    header("Location: $serverName/payments/success"); 
    //exit(); 
} catch (PayPal\Exception\PayPalConnectionException $ex) { 
    echo $ex->getCode(); // Prints the Error Code 
    **echo $ex->getMessage(); // Prints the detailed error message** 
    die($ex); 
} catch(Execption $e){ 
    $data = json_decode($e->getData()); 
    header("Location: $serverName/payments/failed.php?err=" . $data->message); 
    //echo $data->message; 
    die($e);
