Загрузите файл через php в cisco APIC-EM, используя curl

Я пытаюсь загрузить файл конфигурации через CURL PHP на Cisco APIC-EM через POST, но получаю неожиданную ошибку:

//File Upload
echo "<b>File Upload:</b><br>";
$namespace = "config";
$data = array(
"version" => "",
"response" =>
array(
"nameSpace" => $namespace,
"encrypted" => false,
"id" => "",
"md5Checksum" => "",
"sha1Checksum" => "",
"fileFormat" => "",
"fileSize" => "",
"downloadPath" => "http://hama0942.global.bdfgroup.net/network/net_config/bdfbrsao00000000rt02.txt",
"name" => "bdfbrsao00000000rt02.txt",
"attributeInfo" => "object")
);
$data = json_encode($data);
//For Debugging only - Request
echo "<br>Request:<br>";
echo '<pre>';
print_r($data);
echo '</pre>';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_URL, "https://hams1484.global.bdfgroup.net/api/v1/file/".$namespace);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: multipart/form-    data", "X-Auth-Token: ".$serviceTicket));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array($data));
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
$response = curl_exec($ch);
echo "<br><b>Request-Header: </b>".curl_getinfo($ch, CURLINFO_HEADER_OUT )."<br><br>";
//For Output Debugging only - Response
echo "<br>Response:<br>";
echo '<pre>';
print_r(json_decode($response));
echo '</pre>';
curl_close($ch);
echo "<br><hr>";

Это результат:

File Upload:

Request:

[response] => stdClass Object

[message] => Unexpected error

)

Боюсь, что с настройками CURL что-то не так, но я не уверен. У кого-нибудь есть идея, что здесь не так? Я использую PHP7.

Благодарю.
