RingCentral接口请求

Question

我正在尝试向RingCentral API发送请求。文档的链接是https://developers.ringcentral.com/api-reference/Fax/createFaxMessage如果我没有指定faxResolution或coverIndex，一切都很顺利，可以发送传真。但是如果我像下面的代码一样添加faxResolution参数，我会收到与coverIndex参数相同的error "Parameter [faxResolution] value is invalid", "errorCode" : "CMN-101".。我的客户是GuzzleHttp 6.3

    $token = $this->ringcentral->platform()->auth()->data()['access_token'];
    $a = array();
    foreach ($destination_numbers as $number) {
        $a[] = [
            'name' => 'to',
            'contents' =>  $number,
            'headers' => ['Content-Type' => 'multipart/form-data']
        ];
    }
    $a[] = [
            'name' => 'faxResolution',
            'contents' => 'High',
            'headers' => ['Content-Type' => 'multipart/form-data']
        ];
    foreach ($attachments as $attachment) {
        $file_pointer = fopen($attachment, 'r');
        $mime = mime_content_type($attachment);
        $a[] = [
            'name' => 'attachment',
            'contents' => $file_pointer,
            'headers' => ['Content-Type' => $mime]
        ];
    }
    $client = new Client();
    try {
        $response = $client->request('POST', url(config('services.ringcentral.app_url')) . '/restapi/v1.0/account/~/extension/~/fax', [
            'headers' => [
                'Accept' => 'application/json',
                'Authorization' => 'Bearer ' . $token
            ],
            'multipart' => $a
        ]);
        $response = json_decode($response->getBody(), true);
    } catch (\GuzzleHttp\Exception\ClientException $e) {
        echo($e->getResponse()->getBody()->getContents());
    }

下面是RingCentral在使用PHP时的建议。我包含了他们所有的建议，但只需看看关于faxResolution的部分(下降了2/3)

    <?php
// https://developers.ringcentral.com/my-account.html#/applications
// Find your credentials at the above url, set them as environment variables, or enter them below

// PATH PARAMETERS
$accountId = '<ENTER VALUE>';
$extensionId = '<ENTER VALUE>';

$recipient = '<ENTER VALUE>';

require('vendor/autoload.php');
$rcsdk = new RingCentral\SDK\SDK(getenv('clientId'), getenv('clientSecret'), getenv('serverURL'));
$platform = $rcsdk->platform();
$platform->login(getenv('username'), getenv('extension'), getenv('password'));

$request = $rcsdk->createMultipartBuilder()
    ->setBody(array(
     'to' => array(array('phoneNumber' => $recipient)),
     'faxResolution' => 'High',
    ))
    ->add(fopen('fax.jpg', 'r'))
    ->request("/restapi/v1.0/account/{$accountId}/extension/{$extensionId}/fax");

$r = $platform->sendRequest($request);
?>
