我建议使用两种方法来解决此问题：

1. 从错误消息中，您看到的错误类型为PayPal\Exception\PayPalConnectionException。我们有一个特殊的方法getData()来检索关于错误的确切细节。

你可以这样做：

try {
    $this->payment->create($this->paypal);

    $hash = md5($this->payment->getId());
    $_SESSION['paypal_hash'] = $hash;
    if ($this->databaseConnection()) {
        $result = $this->db_connection->prepare('INSERT INTO transactions_paypal (user_id, payment_id, hash, complete) VALUES (:user_id, :payment_id, :hash, 0)');
        $result->execute([
            'user_id' => $_SESSION['user_id'],
            'payment_id' => $this->payment->getId(),
            'hash' => $hash
        ]);
    }
} catch (PayPal\Exception\PayPalConnectionException $e) {
    echo $e->getData(); // This will print a JSON which has specific details about the error.
    die(paypalError($e));
}
