Paypal在调用刷新令牌后返回“400无法刷新访问令牌”

Question

我使用Paypal SDK来授权我的网站上的客户端，但是当我尝试获取access_token时，Paypal会返回400错误，其描述为“无法刷新访问令牌”。

默认示例正在运行。

请帮忙，因为我无法前进。

我的代码列表：

use PayPal\Api\OpenIdTokeninfo;
use PayPal\Api\OpenIdUserinfo;

$refreshToken = 'C21AAHGeO4Ah7vrYzFNmvCxn9wplulKX-TIe17wfWDRIXMPH4MBIRkMN5OCuFUk-QcKBsTD3MWRX3j3tQ4xVcMHLh5pmIl42A';
$clientId = 'AZGKPdDCkeDGNgkje2b__yIWZBUWiDfEifiGJwoiD4ksmCDD4FieN_oW2a82yjcKCyeubAfO2uQZsUwP';
$clientSecret = 'EGwnYPLfXB8NSXCIeJho23kPw9hXxWiP22LaP8gmFjPDL5XX3TGFpEUn1m4ascle7727pX5fWEHAy5V9';
$apiContext = new \PayPal\Rest\ApiContext(
        new \PayPal\Auth\OAuthTokenCredential(
            $clientId,
            $clientSecret
        )
    );

    $apiContext->setConfig(
        array(
            'mode' => 'sandbox',
            'log.LogEnabled' => true,
            'log.FileName' => 'PayPal.log',
            'log.LogLevel' => 'DEBUG', // PLEASE USE `INFO` LEVEL FOR LOGGING IN LIVE ENVIRONMENTS
            'cache.enabled' => true,
            // 'http.CURLOPT_CONNECTTIMEOUT' => 30
            // 'http.headers.PayPal-Partner-Attribution-Id' => '123123123'
            //'log.AdapterFactory' => '\PayPal\Log\DefaultLogFactory' // Factory class implementing \PayPal\Log\PayPalLogFactory
        )
    );
try {
        $tokenInfo = new OpenIdTokeninfo();
        $tokenInfo = $tokenInfo->createFromRefreshToken(array('refresh_token' => $refreshToken), $apiContext);

        $params = array('access_token' => $tokenInfo->getAccessToken());
        $userInfo = OpenIdUserinfo::getUserinfo($params, $apiContext);
} catch (Exception $ex) {
        // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
        var_dump("User Information", "User Info", null, $params, $ex);
        exit(1);
}

var_dump("User Information", "User Info", $userInfo->getUserId(), $params, $userInfo);

代码执行的结果：
